Thanks for the replies.
What I want to find is a silver one with under 60,000 miles for under 20k. They're out there so it won't be that hard (just might have to go a few hours to get one). But, I may have to get a pre-2002 to get that price (they're out there, but rare). Is there any specific reason I should stay away from anything before 2002?
As for building one on Lexus... it doesn't look like there's a single option you can choose at all. After you select the car it takes you to an options package page with only one option package that you must select.
