It is honestly poor design, if you ever pull it out, they get bent and no longer keeps the panel. Chances are - the clips are just stuck in the dash. It is possible to pull them out, bend them back in shape and reuse them, but for me they really feel like single use from design perspective, and even the ones I have bent back into shape still don't keep that trip piece flush... so keeping that bluetac there may be good idea, otherwise it may rattle. Part number for that clip 90468-04157 and LPD actually has them for resonable price https://lexuspartsdirect.co.uk/product/lexus-trim-spring-clip

Yeah - that is what I thought... just a note here - you don't need to replace that plastic, there is nothing wrong with it in your picture, what you need is only the metal clips to secure it in place.

Recommendation - don't get drilled grooved discs... they just make more noise and are easier to warp. I know it looks cool, but apart of looks they are objectively worse than simply solid/vented. You are most likely correct, however the result is the same as just getting any fully-synthetic oil. Toyota does not make it's own oil, so inevitably they are just repackaging it from some supplier and putting their margin on top. Obviously that is cynical view, alternative view - they buy in bulk, make saving and transfer that saving to you... Somehow I doubt Toyota does any charity... maybe it does for it's own dealers, but by the time it is resold to end consumer, the price probably is the same as any other fully synthetic oil.

All great, just change the C3 oil to A5, or A1. Also I would not take Magnatec, already explained why. It is good oil, I just don't like how it turns grey and almost looks like sparkly stuff because of additives.

I don't believe there was ever Japanese seller for such parts. Reason - I don't believe it would be really acceptable from perspective of Toyota/Lexus as they would see it as trademark issue... or copy of their design. So I may be wrong, but I believe it has always been only chinese sellers.

They are when it comes to sensors. Try putting non-genuine or aftermarket o2/labda and the car will not be happy, it may work for few months, but eventually you will need to get genuine Denso. I guess sparkplugs can be included in that list - only ever Denso Iridium and nothing else should be used. There are other bits like ball joints and wheel bearings, where you can go aftermarket, but Toyota stuff "special sauce" is that they just last 10 times the mileage for only 3 times the price. Sometimes there is no option... for example I had A/C low side pressure sensor issue and Lexus just would not sell the sensor - you want the sensor, get whole low side pipe for something like £700+VAT, ended-up buying just a sensor which I am probably 90% confident was fake for £11. But considering "alternative" I thought... I could do it 10 times and still be better off. As far as I know that sensor was in the car for 5+ years without issues. So there are certainly parts that you should use genuine, some others that you don't have to. But some generic parts like filters and oils - there are actually better quality aftermarket stuff. Also brakepads and discs - aftermarket often better if you know what to buy. @HPS13 Hugh et al. - this is forum, anything said here is ALWAYS only opinion, unless explicitly stated otherwise. Perhaps saying you disagree with me on this one was enough? Let me rephrase it - don't buy service items on ebay unless you personally know the business selling them is genuine and can be trusted. Good enough? @T man 545645 - lets not confuse genuine business, like main dealer, which may also have ebay store (say LPD which is Lexus Swindon) with "ebay seller"... aka somebody that doesn't exist anywhere but ebay and seems to sell all sort of stuff... some of which happens to be Denso Iridium plugs for half the price of what they usually cost. Not so sure about "genuine" discs and pads on ebay either, certainly had fake Brembo pads (and not from ebay, but considering how much stir-up my above comment caused I rather not mention the source). But all what I said above should apply - don't buy unless you personally know and trust the business you buying from. I am not going to start another topic... about how reviews and feedback can be bought and how they often don't mean much.

Big brands oil... certainly. Also probably Toyota oil. Something like Mannol - it is not worth enough to fake it, question is more whenever it is good idea to use Mannol or not, but I have already outlined my opinion in that regard.

You know I reckon most of the people get them from same AliExpress... some may pup-up on ebay, but they still coming from china, perhaps even same seller(s) and... yes they are not cheap... always been around £400, even for mk3 style one. And also they don't fit very well, so expect to have to modify both your car and the bumper... mostly cutting support foam, but may as well require crash bar "modification".

Most likely to be counterfeit - honestly, ebay is probably worst place of them all to get common service items, basically those who counterfeit parts won't risk faking some obscure part which may or may not be bought, so they go for large volume items that are guaranteed to need frequent replacement. Almost all plugs on ebay are counterfeit, the one in picture look rough even from low quality picture provided, so hope for them being genuine is very low. Filters... at least in the picture look genuine. I mean you know - I can't 100% say they are fake, but on ebay the risk of fake spark plugs alone would be little too high for my liking. "genuine" Toyota oil to be honest is average quality at best and when it comes to oil I would focus on replacing it more frequently (ideally twice a year every 6,000 miles) than getting best oil possible and keeping longer. Logic is quite simple here - when engine was designed and car was made 15+ years ago, even best oil was worse than cheapest oil sold today. So as long as you put fully synthetic oil it should be fine. I am not 100% sure, but I believe standard Toyota oil is part-synthetic (or at best hydrocracked), so getting literally any synthetic oil will be improvement. I would say - it is fine to go for aftermarket parts, some aftermarket parts far exceed quality of genuine Toyota parts some are worse quality e.g. Bosch oil filter looks literally luxurious compared to Toyota genuine one... is it overbuilt for the task... maybe, but for £8 I rather have overbuilt Bosch than go for OEM Toyota for £17 which is also quite obviously worse quality. But the worst deal of all is to go for counterfeit "OEM", because then you end-up paying OEM prices and getting the absolutelly worst possible quality part. If you want to go for genuine parts then LPD has decently priced kits: https://lexuspartsdirect.co.uk/product/lexus-is250-phase-2-service-kit/ Sure it is ~£30 more like for like (major service pack has same items as the one on ebay for £208), but it will be 100% genuine. What I would do... 20 litters can of fully synthetic 5W30 - you can get that for £40-50. Brand doesn't really matter. If you really want to treat yourself Mobil1 extra long life is quite good, Castrol Edge (Magnatec I don't like, it turns very dark within 100 miles, it does have additives, maybe that is why, but also it is hydrocracked and not true fully synthetic) - opieoils is good place. Otherwise just any fully-synthetic that has all the required certification. I happy put Mannol fully synthetic and have done so for 100k miles now (on different cars) no issues. This one is one ebay. Bosch oil filter from autodoc (the one that has fused rubber reinforcement) - £8. Cheapest cabin air filter that has activated charcoal (activated charcoal only last maybe 2 months at most anyway) often that costs like £3 - autodoc. Air filter rarely needs replacing, perhaps once every 3 services (even Lexus does not replace them in their fancy £500 oil change), I would get genuine Toyota as they seem to be the best for the price and you can get it from autodoc as well - ~£16. Spark plugs - LPD... and they can go for another 80k miles, it is £94, but it is genuine. Alternatively, if making larger order from amayama they are only £6, so £36 for 6, but it is not worth ordering just spark plugs, because with delivery it works out ~£108 (yeah... deliver more then the plugs). That said LPD also sticks probably £5 for delivery. If getting from amayama, then at the same time I would also order 5x washers for foreseeable future and new drain plug screw - that is £6 for all 6.

I think I know what you mean - it is just a bit of black plastic that has a little light in it? No - sadly one thing I left in the car was HVAC unit as it is real pain to remove (thinking about it... I may have made a mistake not putting the effort to take it out). In other hand I do have one for GS300 and they may be identical... I need to check. EDIT... Yes they are, so yes - I have both things:

cool - let me know. I should have all the bits that goes around the glove box.

Basically, a passenger knee airbag? I guess I can remove the cover from the airbag (will need to check). Yes - I do.

No front badge... also if it costs £148 from amayama, then LPD it will be at least £500.

there are, they are least of your worry, you just lift them out of the place.

You need to remove everything from central console/tunnel cover. The annoying part is just bunch of cables that are clipped into the shifter assembly and it is kind of hard to pull it out thought the cables. So it will looks something like that (you can see the covers are just lose, but not fully removed): Also you will need to undo the bolt for shifter linkage. It is possible to do it from inside of the car, so you don't strictly need to go under the car (although obviously it helps if you have a lift). If you want to do it from inside the car, then move the linkage all the way forward (basically it would be in D position), then you can pull the linkage inside the car and I think it is 12mm or 13mm nut that you can reach under the linkage. I would advise to mark the position of linkage before you remove it. And then when reinstalling, don't forget to push linkage all the way back. I would say good 2 hours job without rushing (probably can be done in 30 min if you done it dozen times in the past), really looks horrible and seems like car will never come together again, but it is not really "hard" as far as working on IS250 is concerned, just loads of pieces of plastic, vents etc lying around (generally working on IS250 is more complicated than most other cars).
