In my area, I believe I got very lucky. On Christmas Eve I was looking in a local dealership at the 2011 RX series when I found out they had a "few" 2010 which were used as loaner vehicles for the dealership. Long story short, I ended up buying a "slightly used", but titled as new for warranty purposes RX350. This vehicle had 8400 miles on it. Original sticker was 48,800 plus. Not sure about which packages it has, but obviously NAV, HID light system, moonroof, wood wheel and knob, AWD, sense wipers and lights, 12 speaker package, back up camera, XM radio, bluetooth, cargo mat and net, and body side mouldings. (They put these on all their loaner vehicles)
I ended up getting this vehicle for 38,000. I also got 1000 back because I own a 2006 es330 and had a 2003 es300 before that. I think it was that Lexus for life program. Anyway, I have had no problems with the vehicle. Can't see any indication of abuse or neglect. The 5000 mile sevice was done by the dealership a few months ago, and the 10000 was thrown into the deal, which I just had done. Vehicle was detailed and spotless.
