A friend of mine bought a 2000 LS new. Ever since day 1 there have been problems with it.
As soon as it got out of warranty, it seems the amount of problems has escalated. It's to the point where she hates driving her 4 year old car because everything is breaking on it. Stereo died, rear end started howling,
suspension clunked, driver's seat motors died, windows didn't work, and other nagging things. Nothing majorly mechanical, but it was no fun to get into a basically new luxury car and see it falling apart. She took care of it as well, just little things were always going wrong.
She's about to soak $1500 into it just to fix it up enough to sell it....for probably a little over $10K
It's hit or miss really with any car. Not every car of every model has their problems, but you cant rule it out.
