I'm a New York attorney, and I'd say you're in great shape. There is no ambiguity here - the contract clearly states that the paragraph is not applicable. If GM did try to argue that the clause is ambiguous, then they would face the legal principal that a contract which is ambiguous is construed most harshly against the party which drafted the contract, and here that would be GM. But again, it's not ambiguous. They could try to argue that the clause is a mistake, and that the industry "custom and usage" would impose a mileage amount, but they are bound by the terms contained within the four corners of the contract, and a court cannot look beyond the written terms of the agreement. Legally, my friend, you're golden, in my opinion.
