I purchase my GS 300 used with 36,000 miles, I now have 106,000 miles and notice no difference than when I originally purchased. Outside of brakes and general maint. I have had absolutely no problems. It is a great car. I just took in to service for tuneup, and brakes and intend to keep several more years. The newer cars do not really turn me on in comparison to what I already have. I have the luxury I want and performance as well in a car that is now 11 years old. I don't think other car manufactuers can give me the same satisfaction after 11 years.
Comfort and performance.
Trunk space is the only draw back but have learned to pack accordingly.
