I know you posted in April but if you're still in the market for a 97 or a 98 I can tell you that if taken care of properly that car will last a very long time. I bought my 98 with 41,000 miles on it. From since the day I bought it, I religiously change the oil every 4,000 miles and I only use synthetic with a Mobil 1 oil filter. Mobil 1 Oil filters run about $12-13. I also have the tranny serviced every year. There is a tranny filter kit that is sold that is a filter/seal/tranny oil. My mechanic recommended I do this every year. Apart from the 60,000 service and Timing belt...I've had no issues with this car...It runs beautifully and is very reliable.
By the way my 98 now had 82,000 miles on it...at the rate this car runs...I can put another 250,000 on it with no problem.
