Just be straightforward. “I like the car and would like to buy it, but it’s been on the lot for eight months. That’s unusual for a low mile Hyundai Accent at such a decent price. Have there been any issues with the vehicle of which I would want to be aware? Has it had any mechanical problems or bodywork that might not show up on a Carfax report?”
At least they’re confident that it’s been fixed whatever it was, if indeed there ever was anything wrong with the car, given the Certified warranty.
BTW....thanks for the advice
Lets say this is benign and the car is okay (just been sitting on the lot for 8 months). What would cause this? Nobody interested, not pushed hard enough by the dealer, bad luck? Nibbles but no bites?
