New to this site, just found yesterday :( but I have owned my 2001 RX300 since day one Sep 20, 2000! I turned 161,000 miles this morning and this has been the best car, I ABSOLUTELY LOVE IT!! This is what I have done to my car since buying:
new tires Michelin March 2002 36,600 miles
replaced window run Oct 2003 68000 miles
replaced brakes April 2004 84,000 miles
replaced antenna motor, peeling roof rack, timing belt and some other belts Sep 2004 97,900 miles
replaced headlight and rear side marker light bulb Dec 2004 107,400 miles
new tires Michelin August 2005 127, 000 miles
replaced brakes, rear brake light, replace seal, crankshaft - rear main, reseal leaking oil pan gasket,
April 20, 2006 155, 000 miles
I have never owned a car for this long or with this many miles. Thought about trading for a new one, but I think the 330's are terrible, I hate getting one as a loner car.
I do have a few minor annoyances:
seat backs occassionally pop off
the pop up cup holder is broken again and will not pay to replace
all in all I am very pleased!
