I am going to be looking at a 1989 volvo 740 turbo and it has 111,000 original miles, and i was wondering what i should look for on this car when i look at it..

if there is any signs that could give me the red flag not to buy it..

 

oil leaks, smooth idle, smooth shifting trans, overdrive function, rotor shake, and overall trim inside and out like door panels, window power regulators, etrc..
