For third party companies, here is what ya need to look out for. OEM parts or aftermarket, what labor rates will they pay up to, is it a reimbursement plan or do they pay the repair bill to the service center, is there a maximum payout, can they cancel the plan for any reason, and how long the company has been around. You'd be surprised as to how many times we have someone livid in service because they bought a contract that only pays at $50 an hour labor and won't use Toyota parts. If that contract can satisfy all those then I would jump on it like a fat kid on cake!
