Do not assume "your lawyer will handle it," or "you will just get your money back." In many states, as-is means as is, and your lawyer will not get anywhere.

When you buy a car with no warranty from a dealer 1,000 miles away you should assume you got what you paid for - a car with no warranty from a dealer 1,000 miles away. Even if the seller is required to offer warranty, that won't generally cover the cost of shipping, and his obligations under any required warranty are usually very limited. The lesson: Do not rely on any implied used car warranty.
