I would do some reading here on the forum to become familiar with these cars. They don't have "timing belts" and the chains are rarely a problem. In fact, the engines are probably the sturdiest part of the car if maintained properly. Many 9c1 and 9c6's had 400-500,000mi in police and taxi duty without engine overhauls. Your biggest risk is the transmission. If it has been rebuilt, get the details. If it hasn't, it probably will need it within the next 30-50,000.
Have it checked by someone who knows what they are doing. Needless to say, you should Carfax the car and run it on compnine.com for details on the original equipment. Good luck. That price is way too high.
