Just picked up my 2002. 41,000 miles. No squeeks or rattles. Forget using car in snow. Run-flats are somewhat stiffer and do wear out quicker from what I hear. I am thinking about getting non runflats. Run flats cannot be repaired. If you are on a trip and get a flat, getting to a gas station or dealer is usually not a problem. The problem is if they have the tire you need in stock. Price, at least $300. Expensive flat wouldn't you say. Around 10-15000 miles. If you buy snow tires, you will have to get additional sensors for tire pressure or put up with the bells and whistles of not having th sensors hooked up to the computer correctly. If you buy sensors from someone else other than Lexus, expect to have Lexus match the tire to the sensor for a charge. That is the only time the bells and whistles will stop. rom what I have read, each sensor has a battery which does expire. When battery dies, it cannot be repalced. You have to buy a new sensor. Possibly a better place to buy would be on ebay. Gas mileage is good depending on how you drive. Right around 25 mph. If you decide to change to non-run-flats, a spare and all the accessories will cost you around $650. Saw one on sale from a Lexus dealer in Texas on ebay. Of course, there goes the little luggage room that you had. Looks of the car are awesome. The certified warranty (if you buy from a dealer) is the way to go. BUT!!! It is not transferable.
