Automotive Forums  Where Car Enthusiasts Go to Discuss Cars Online

Ok, so I'll be getting my first car in December, and my parents and I have narrowed it down to the following:

1. 2001 Audi TT Coupe      33,000 miles
2. 2007 Scion tC                  39,000 miles
3. 2007 Saturn Sky                9,000 miles
4. 2007 Pontiac Solstice       3,000 miles
5. 2006 Volkswagen Jetta  31,000 miles    

How would these affect insurance costs, and how would repair/service costs be for them? In other words, which would be the cheapest, and most expensive in the long run, and which one is most recommended for me?
