Hello folks,
Jumping in a bit late here and apologies for that. My only negative point on my 600h is the small boot but it is a small price to pay for all the pluses, unlike on the GS450h I once had for a week before I realised my error and returned it to get back into the RX400h I had traded in. I did not get on with the stiff suspension on the 450h on our rough roads. The 600h is super smooth, like the 430 and 460. Quite frankly I would be happy with any of these cars.
I do not find parking an issue, partly because I tend to be picky on where I park anyway but I have been in fairly tight car parks - Bentalls Centre Kingston, for example, and it was a breeze. The lack of anti roll bars on the 600h L might be a problem for those who like to test bends at high speed. For me, I like long drives on the continent and the car is perfect for that. I can get up 4am Saturday morning, drive to Follkwstone to get on the 6:20am train to Calais and then run the car in Brussels for 10am and get back Sunday evening and Feel as if I spent the weekend at home on Monday morning . Driving to Rome or Nice is not a bother in this car. (We won't talk about the petrol bills but 32MPG is pretty good in a 5 litre V8)
I love the RX400h too and is equally impressive in different ways.
I am biased though, I just like Lexus, especially the service excellence the dealers provide. I do have a very soft spot for the Mercedes S class and CL too but the dealers really ruin that experience as do the reliability of Mercs compared to Lexus.
