looks like a real nice car. I sold my 87 w/ 60k miles for $9k. Thats a good price for that car, try to bargain lower. As for the chain and tensioner. 100k miles is the mark but there is no harm in doing the job early and taking preventative action. Better to spend $500 now then $5k later for a new engine
