The 1.8T engine has a timing belt where the VR6 engine does not. You should expect to spend around $750 to $1000 on the timing belt depending on what is replaced and where it is done. You should be using synthetic oil in either case no matter what engine you end up getting. Expect to spend around $60 to $80 for a oil change. You can do it yourself for much cheaper however.
