If someone can buy a 2006 version of your car for $20k this summer, I think 14k is high expectations, despite what KBB/Edmunds says. But, it doesn't cost much to test the market. Sticks suck for resale.
Depreciation on your car vs. another $10k-12k car is probably very close. Refinancing your loan balance (dunno what that is, but say $12k) for a longer term would effectively do the same to your cash flow situation if you need it. How much longer do you have to pay for it vs. how much longer do you expect to purchase the next vehicle? If you did pay the 6s off in say 2 more years, no payments after that starts saving up quickly plus the value of the 6.
I guess I'd look more for a <$3k domestic with good track record.
