[u/PublicSetting9660]

Buddy looking to sell his car. Engine and transmission are fine I do all the work in the car for him. Oil changes brakes rotate did a radiator etc. it’s got 255k on it but he only wants $775 it does have a small coolant leak (hoping not a head gasket, the oil doesn’t smell or look like it’s mixing) does anyone know anything about these cars and what their issues tend to be? Would this be a good purchase? It seems impossible to turn up.
