Hi
My advise is only buy a second hand low mileage motor from a full Lexus dealer as the car is prepared as new my 3yr old 20k was delivered as if out of box,stuck private plate and it looks like a 2002 model, there ruling is that any car they sell must be as new or if not better, very high standards, all my stone chips were removed and alloys re-ground better then new,also the years warrany you get far out ways that of a normal dealer and what with the Cd player being a little like a women,I would recommend this route as youve read 1: Pitting of Alloys if this happens they will change them. 2: Stone chips, soft paint work, these are the only things i can fault this motor for other then this AMAZING !!!!!!!! go get one ...still rear sight on roads .....
Remember resale value is always going to be high as in demand... All best. B)
