Should I Trade my 2003 Jetta for a Scion tC?

I just recently bought an 03 Jetta (July 17th), and have had a couple small problems with it. (Gas on fell through so I can open my gas tank, head light is out) Its making me worried, and I'm now seriously thinking about trading it in. I'm looking at 05 or 06 Scion tC.(Hoping I can afford it) What do you think?
