The clue is in what you found. If a flat battery charges very quickly it has a low capacity - and is effectively U/S. All batteries gradually lose their capacity to store charge - usually failing after 5 - 8 years. A good battery will take quite a long time to charge i.e. if totally flat 100 Ampere-hour battery is charged at 4 Amps it will take 25 hours to reach maximum charge. The battery indicator only tells you what the battery voltage is. This does correspond to the amount of charge for a good battery but does not in itself give any clue to whether the battery is actually good. The same applies with Hygrometers built into batteries and using Hygrometers to measure the battery acid - this can only tell you that the battery is as charged as it could be given its remaining capacity - which could be minimal and still give good Hygrometer readings. Only a proper charge/discharge tester can evaluate if a battery is good or not. Realistically, most Garages do not have proper charge/discharge testers or do not understand how to use them; so the best clue if you suspect the battery is dying is to check the battery voltage by using the battery indicator to check the voltage without the engine running an hour after parking up for the night, and again the following morning. The indication should scarcely drop with a good battery. Also if you do not want a dash-cam to operate when the car is switched off, wire it to a fuse/circuit which is only "live" when the car 's systems are switched on (the feed to the sound system is an example). In these circumstances devices like a Lukas 290 is completely un-necessary and just adds expense and an unreliability factor to the equation.

If the scratch is so faint that you can see it in sunshine but can't feel it at all with a fingernail, jewellers rouge (available on eBay etc.) may minimise the scratch without doing harm. You may need to use a power buffer/mop because the rouge is a very fine abrasive and cuts very slowly when applied by hand. It is also very difficult to get splashes of the rouge out of clothing. The compounds used to make modern windscreens may be tougher and thinner; but particularly when the windscreens are new and before the action of light etc. on the glass effectively modifies the surface, are much more vulnerable to scratching by whatever the wipers etc. pick up from microscopic grit and brake-dust particles thrown up from roads.

Perhaps its because I'm getting old (no! I've actually got old), but am I alone in thinking that Lexus have dug too deep into the ugly bucket to come up with the looks of the RCF? I think it is just too much "in your face". All the their current crop have a touch of the 1950's Dan Dare look about them with too many whiplash lines and style points as if conceived by a huge committee where everyone was able to add their own favourite styling cues irrespective of the effect on the whole. And overdone on the RCF - perhaps today's take on the huge tail-fins and tons of chrome of America's yesteryear. For me, less is more. By chance, above this a picture of the IS200 which had timeless, subtle stying and still looks good and not desperately from nearly two decades back. I don't see that in the RCF. I am not surprised Top Gear didn't like it. They didn't like the ISF either - I think wrongly with the ISF with their twaddle about it constantly changing gear, and maybe time will prove them equally wrong about the RCF whether it is ugly or not.

Beware of relying on the TomTom for ultimate speed accuracy, errors exist due to its update rate and straight-line-projection calculations, it is probably not much better than the speedo.

There was a lot of initial demand for the Ultrasonic blue which didn't become available until quite late - by which time it was no longer as fashionable and less than a dozen have been sold in the UK. Rare - yes; desirable not necessarily.

With only 225 or so ISFs on the UK roads, most registered before 2010, and only 4 sold in 2014; you need to weigh-up the importance of the various upgrades. The mechanical LSD makes very little difference over the very capable electronic version except in competitive driving. Some will prefer the slightly softer suspension on later models. The boy-racer ultrasonic blue colour was in great demand from non-ISF buyers and only became available on later models with very few sold (particularly with the white leather upholstery). The steering-linked headlights were dropped on later models - it was no great advantage for night driving anyway. Late models have better audio connectivity and SatNav, plus improvements in instrument and control layout. There are no UK options except the sunroof, although for a while the Mechanical LSD was optional. ISFs seem very reliable and long-lived, so you pays yer money and takes yer choice.

The wheels are made by BBS, but neither BBS in the UK or USA seem aware of this (so assume it must be a Japanese subsidiary) and said in any case they would not release the paint colour code or supply any touch-up paint. In fact they were completely unhelpful and ignored enquiries unless pressed. For tiny scratches and slight kerb/rim scrapes, Gloss black touch-up from Halfords barely shows - or at least looks better than exposed bright metal on these nearly black wheels.

The Lexus diesel engines never had the agility of response needed for the technology used in their auto gearboxes which were closely integrated with the electronic control systems for their petrol engines. An auto gearbox unique to the IS220/200 range would have had to be developed; but their emphasis on low emission vehicles shifted towards the greatly superior hybrid technology.
