When life gives you a lemon …
To qualify for the MA Lemon Aid Law, your vehicle must fail an official Mass safety and emissions inspection within seven days of purchase.
Next, you must get a written estimate for the cost for the inspection-related repairs. If the repair estimate is for more than 10% of the purchase price of the vehicle, you can get a full refund from the seller (private party or dealer).
To get a refund you must return the vehicle to the seller within 14 days of purchase with a signed statement by the inspector of why the vehicle failed, a copy of the estimate and a letter telling the seller that you want to cancel the sale.
