Ha ha. Not sure where you are? KC? That's only 8.5 hours. Breeze.
The good news about buying a used car is there is so much more room to negotiate at most traditional used dealers.
Dealerships make a lot more off used cars than new. Go in late on a Saturday night. NO salesmen wants to be held up on Saturday night not to make a deal. One hour before closing time and you're good.
Can't wait to see how that itch gets scratched.
