And, there's nothing you've described that would send me running for the hills. Any car that's 16 model years old is going to have some issues. Those don't sound particularly bad. The main thing is to get the car into a Volvo service person you trust and pay them to go over the car. Mine (who was a Volvo-certified tech for years before opening his own small shop) only charged 50 bucks to thoroughly go over the car, including compressions tests, etc. He wrote up everything it needed, with costs, and I used this to negotiate the price down. Later, he collect the money to do the work. A good arrangement.

The car has been wrecked - so what? The important thing is it has been repaired. Find out where the remaining/new problems are and what it's going to take to fix them. Make an offer. Drive away happy!

Love both of my 92 wagons - perhaps the best all-around cars Volvo has ever made.
