The Used Vehicle Warranty law doesn't apply to vehicles with over 125,000 miles. However, that's a different statute. The Lemon Aid law has NO mileage limitation. You don't have much time, but if you act right away, you have a right to return the car for a full refund. G. L. c. 90, Section 7N.
What the law says is that, if you get the vehicle inspected within 7 days, and the repairs will cost more than 10% of the purchase price, you have 14 days to return the vehicle to the seller and notify them in writing that you're exercising your rights under the Lemon Aid law. You can agree to let the seller do the repairs, but you don't have to. All you have to do is get him a written statement of the reasons the car failed the inspection. And the disclaimer you signed is of no relevance, because of the Lemon Aid Law.
Here's a plain English explanation of the steps that must be taken - but the 14th day is Saturday, so it's better to take the written statement to the dealer than to try to mail it. It might help to also print out and take the statute with you.
