I used to own a 98 VR6, I loved the car, it was a good cruising car. Stick with a VR6 model you will be happier with that model. The car does not get as good gas milage as say a honda does, but that is to be expected with a german car. There are a lot of good mods to do to the car, first thing I did to mine was the suspension, as the stock suspension was super soft, and the car had a lot of body roll to it stock. The other thing is working on Jetta motors especially VR6 motors is a bitch, and I mean a real bitch, nothing is easy to get to, I spent a weekend getting the damn headers and exaust in. Other than that stuff the car ran awesome, no major problems in the 25,000 miles I had it. The interior is super comfortable, not race seats or anything, but more luxo style on the interior. Chicks dig the car, but that is because a lot of people label it as a "chick car" I still loved it and miss it. Had it not been totaled I would have auto-x'd it. I have seen them at the auto-x's and they do fairly well, I have seen some VR6's lay down so times that are up there with the swap hondas.
Good luck man, the VR6 is a pretty sweet ride.
