Pity your Wife doesn't like silver. I have just reduced the price of mine to £11,500 as new car is imminent. I doubt you will find a more genuine car. The details are further down this page/

Michelin Cross Climates. Mine have done 10000 miles since October and are barely worn. 

I have read quite a few reports (mainly Honest John] stating how Michelin Cross climates improve ride comfort and noise levels, but none for an RX. Have you experienced notably improvements with these tyres? My 450h is shod with Bridgestones and I find road noise to be unacceptable, compared with previous Lexus' I have had.so, whilst the Bridgestones are not exactly at the end of their useful lives, I am tempted to change them. I would be grateful for your response. 

Thanks for your post Farqui: 450h-I Silver/Black. Photo to follow, when and if it stops raining!

Just bought a 2010 450h (49k), to go along side my SC 430. Only done 300 miles so far but very pleased with it. I fine vehicle that's a credit to it's previous owner.

Thanks for this Colin. Have to say that in all other respects the car runs very well indeed. It's now done 70k miles id that helps with possible reasons for the problem.

Hi Colin, I have now tried with Aircon off but no discernible difference. Also tried in PWR and Norm modes but no difference. It's as if the wheels are driving the engine. Throttle position monitor / gearbox?

As a matter of interest and to, hopefully, increase my knowledge, what was your thoughts behind the Aircon on and off?

Regards

Marc

I'll try this Colin

Thanks for your post Colin. "touching" the breaks doesn't seem to make a discernible difference.

I have had my SC430 (6 speed) for a few months now and have a problem which I hope some of you cleaver people may be able to throw some light on. The engine idles smoothly at just under 800 rpm but when coming off the throttle at say 40mph for this example (but it's the same at any speed) the revs stay at 1100-1200 rpm so the car does not slow down - taking some 200m reduce speed to 30 mph. However, if the brakes are applied (necessary!) firmly, the revs drop to the normal idle level. Is the throttle body the likely culprit?

Any help will gratefully received.
