Thanks guys for the info But like saying I know very little about cars. So what are the engine types I should get if please give me a list of types and if its some other type then I would turn it down. Also is there anyway I can be sure he tells me the right engine type or do they tend to lie about this too? And as far as warranty is concerned what should be covered on a used engine warranty (within reason) so if he tells me what the warranty covers I know if he's screwing me? I know so little I need to make sure. Thanks again!
