I always have everything repaired by a Cert Volvo mech. I then ask a higher than usual price. I just sold a 97 Turbo for $11,600 with 127K on it. When they start to negotiate, i show them a print out of the repairs done by the Volvo dealer. I also preview most of my competition. Haven't failed to sell a 1985 Mercedes, 1987 BMW 735I and the 97 Volvo for top dollar. I'm not hoping to sell the cars. I will ALLOW some one to buy them. Pretty arrogant I know, but it works. I have looked at several cars when I put mine on the market, and when the prospective buyer says " I am also looking at a red 97 whatever", I say oh yes, you mean the one that has not had X Y and Z done to it.
