Good choice with the MkIII jetta!!! I've got a VR6 MkIII and i highly recommend one! The only downside i have experinced is that they can be confusing to work on because German's are weird LOL ... AND they get horrible gas mileage! At first i was getting an average of 17mpg in the city and 25 freeway, but i changed my oil to Royal Purple and now i get 19mpg in city and 29 freeway
