Hello, This is my first post on the forum. I have been searching on all the popular classifieds for a well maintained Lexus GS 300 from 1998-2005 regardless of mileage. I have been driving a Honda Fit/Jazz back home and after experiencing a refined ride I would something comparable here and after some research I have settled on this car since it has a long wheelbase, has 4 doors, has the Japanese reliability while not being overpriced like the Toyota and Honda market is (The 2JZ is an added bonus) How is the Mileage of the car (I know its a straight 6 and not a 4 cyl)? How easy are the spare parts for it? How much more is its maintenance (compared to other dailies) If anyone has any advice/recommendation I'm all ears. Thank you
