considering purchasing car above,BUT it has some issues appears to have blown head gasket(oil leaking onto exhaust manifold), front wheel bearings need to be replaced, tie rod ends, car has only 70,000 kms. the only part that scares me is the head gasket issue, especially with mileage on this car. anybody have any idea how much $$ it would take to get this back into shape, mecanically? Really appreciate input.
