My girlfriend is thinking about purchasing a 2001 Lexus IS 300. I was wondering are there any "common" problems? And, the car she test drove already had 76,000 miles on it. When (what milage) does the timing chain/belt (don't know what it has) need to be replaced? I'm not into the whole Toyota/Lexus thing, so I'm not quite sure. And, any negatives about the car? Any help is good help. Also, any forums that I can read up on before she buys it? Thanks in advance.
