Hello.. I just purchased a 2006 GS300 AWD, black/tan, with 27,000 miles, fully loaded with Navigation/Mark Levinson, parking sensors, etc. I got it from a mercedes/Bentley dealer who had it cause someone traded it in for a Merc. I paid $30,500, with an out the door price of about 31,500 (including tags, taxes, fees). They wanted $34k. I think I got an awesome deal. never been in an accident, paint was clean, except for some minor chips in the front.
I do have to take it in to Lexus to check on the Sunroof (one click open does not seem to work, i have to keep the Open button pressed), and I guess the side mirrors should go down when reversing...they don't.
I used to have the 2002 GS 300, but the newer model is so much better.
