1. The timing belt needs to replaced at around the 90,000 mile mark, along with the water pump.
2. They are pretty fast despite only having 188 HP. I don't think i've lost a race against a car with similar horsepower.
3. The Lexus Premium Sound System is a good sound system, better than most.
4. Leaky valve cover gaskets!
5. I'd go with the reliability factor. I've seen Lexus' cars with over 250,000 miles and still running strong. Your getting a 11-12 year old car that was only driven at an average of around 7,000 a year!
