Maintenance may be pricey these days, but car repairs can be even more expensive. If you have only one big repair bill that is covered by your extended warranty, an automatic transmission failure for example, then your policy just paid for itself. Repairs to transmissions are frequently close to the cost of a remanufactured unit, which can easily be $2000 or more to replace. How about an air-conditioning failure? Based on typical repair costs, figure on spending $700 or more to keep your cool. Even if you have a $100 deductible you’re still way ahead of the game compared to footing the entire bill yourself.
