First, I love the GTI.
Second, I love my truck more, lol.
All jokes aside, I say if you want a sportier car and better gas mileage, its a good deal. They drive amazing on the roads, like a go cart.
The interior seems to be made with quality materials.
What I would do, is fulfill your dream with a VeeDub, but wait until after the winter. Do you remember last winter? Being in Jersey,I know you had a lot of snow. I love not having to touch a shovel when I need to go somewhere. Last year the blizzard on December 26, when everyone was crying, I drove to Boston to drop off a friend when they shut the airports and busses and everything else under the sun.
Keep the truck until say February /March, you can also get good deals on them around that time as well.
My friend has an '01 Jetta, no major issues with it, like 180k miles on it. (Like was mentioned, working on it can be annoying since they have to cram a lot into a small space, just ask the CRD guys, lol.)
Either way, do what you feel like.
P.S. - the Honda Fit is an awesome little car. Deceivingly roomy, awesome has mileage, and cheap!
