are there additional costs if purchasing a used car from a dealer?

It's a 2008.... I seriously doubt that they would offer anything more than a 90 day or 12 year.. usually standard. What is typically offered is a "mechanical breakdown insurance". If I were you, I would first look at financing this from a credit union...they offer the best rates and I got my mechanical breakdown insurance through them for one third the price the dealership wanted.... same coverage... although I didn't need it...it's a peace of mind thing... don't try and justify that. Finally, look at the Carfax report if you can....how many miles and what price are they asking.... LOOK, condition is EXTREMELY important in a used car, it's everything. Good luck.

GuruDYSCY- As I mentioned a few days ago.... condition is everything when you're looking at a used car. Ask for service records, and see if it was serviced at a dealership or other qualified garage...it makes a difference. Clues like new tires, immaculate interior and exterior....all systems working, will give you a sense for a car that has been well cared for....if you find it's in rough condition with the seller saying that it just needs a little fixing and TLC... walk away... I'd rather pay top dollar for a car in 100 percent condition than a beater.... Good luck
