I've owned my LR RWD model 3 for 18 months and I want to buy an LR AWD model 3. My friend has offered to buy my car, but now I'm afraid I'll have to pay back the $2,500 rebate back to the state because I have owned it less than the required 30 months. Does California pro rate you, or do they even check? Anybody have thoughts or experience on the matter?
