Have they applied the same NCB on the GS as was on the SC?

Go for it! They are offering to 'freeze' the premium for three years (well they have on the policy I took out on the RC300h. They were cheaper by far than my Direct Line renewal and any other quote on the web)

Drove my Lexus through some torrential rain today, plenty of surface water and spray. Had to drive through a flooded underpass, water was approx sill height. I waited, much to the annoyance of following cars, for a gap in the oncoming traffic then drove very much on the opposite side of the road not because the water might have been shallower there but to prevent any oncoming vehicles entering the flood and causing a bow wave. Car went through without problem. Not something I would want to do too often...

Looks aftermarket Have you tried pressing it?

It's mapping data stored on the Sat nav. So may be out of date, depending on you mapping version. On my 2019 model I can add locations on the fly, as I see them. Not sure if this is then just stored locally or shared via the Lexus server.

Just correlated the beeps with passing cameras initially but got it confirmed by my dealer

Double beep is the speed camera warning, approx 0.5 mile from the camera. It only warns of fixed cameras. There is no documentation regarding this function. Only now in my 2019 model is there a mention in the owner's handbook

Hybrid system must be ready, or the car wouldn't start, it's the hybrid electric motor that spins the engine to start it. How long are you driving before saying the hybrid system doesn't engage (by which I understand you to mean the car won't go into EV mode)?

The best protector is, IMHO, prevention... To clarify, regular gentle cleaning will prevent deterioration and accelerated wear.

Yup, just the springs are offered and according to the official Lexus configurator they work with the stock shock absorbers, which on the RC350 F Sport is AVS Hopefully the link will work https://www.lexus.com/build-your-lexus/#!/zip/90263/series/RC/year/2020/trim/9213/buildId/103/option-details/S2/my-dream-car/{-x-:-05C1-,-i-:-EB04-,-a-:[-S2-],-p-:[],-z-:[]}

When buying my 2019 RC300h I enquired of my dealer if they could source lowering springs for the car. As Lexus do sell and fit and still cover under warranty lowering sets for the 350 and RC-F in the States, they don't for the hybrid, as they don't market the RC300h there. My dealer enquired with Lexus Japan and was informed lowering springs were not available for the 300h

A number of Lexus models (my RC for certain) have a rear camber that will wear the inner edge of the rear tyres. This is perfectly normal. My RC had a full geometry check at each service and at nearly 3yrs and 17k miles the tyres were showing inner edge wear. This was pointed out to me by the service manager and explained it was normal. One just has to keep an eye on the wear, not just a glance at the centre and outer edges. Regarding the bolts being seized any good mechanic would be able to free them off and replace with new.

Yep all modern leather is PU coated (except very high end specials) and doesn't benefit from the use of conditioners. In fact conditioners can create the very problem they are supposed to prevent. The conditioner just sits on the surface of the (coating) leather and attracts grit and grime. This then get 'massaged' into the folds and creases of the leather, wearing away the coating and causing cracks. These then attract more dirt and turn dark/black. I had my Merc retrimmed with a naked nappa leather. The seats felt wonderfully soft and smelt great but they were horrendously difficult to keep clean. Never again.. Proprietary cleaners are generally ok but simple luke-warm water with a little wool detergent works equally well. That all said I use the Lexus executive leather cleaning kit on my RC.

Dual is the control for tandem or individual temp setting. Do you have your smart-key linked to the climate control i.e as you unlock/open the door the system resets the heating control (plus other memory controlled things, such as seats and mirrors) to the last set options?

How about the obvious, your local Lexus dealership?

If you go to the size suggested your speedo will under read massively, you would be doing nearly 77mph at an indicated 70mph. The difference in rolling circumference is 6.9%. The recommended max is 2.5% https://www.tyremen.co.uk/tyre-size-calculator

Sticking them on with tape designed for reg plates is the better way to go. They will be more secure, less likely to be stolen and won't promote delamination/discolouration.

Doesn't your insurance have glass replacement cover?

Doesn't appear to be the case in the RC. The handbook states operation condition is the Power switch is in the ON mode.

If the potential financial lose is great enough the insurers will send an expert to interrogate the ECU and any change in mapping will be discovered. Do not believe those claims from remap companies that their remaps are undetectable.

No offence meant but you haven't put the bulb in upside down? I know it's possible on some (MB) models, maybe also on the LS?

Must admit to thinking all hid lights were projector?

Check the condition of the engine and transmission mounts

All automotive leather is coated and sealed, so conditioner is a waste and possibly detrimental to the finish. Use any proprietary cleaner or simply use luke warm water with a little wool detergent. Don't soak the leather, dry naturally.
