As of 3 days ago I am a proud owner of a 2006 GS300. I also had been looking for ~2-3 mos for the "deal". I found one loaded (Nav, parking sensors, ML, etc) with 44,000 miles for $24,800. My question is...should I have paid a little extra for an certified pre-owned, or did I save enough $$ to cover any (hopefully rare) issues I may have?
