Thats a lot considering a tranny or rear end rebuild is about the same price.
Remember only 7% of people keep a car for 100,000 miles.
Most people who buy a a domestic car on average spend $200 on repairs (excluding wear items) for the first 80,000 miles. Remember that all wear items: brakes, clutch, lights, whiper blades, stereo speakers, tires, fluids, etc. are not covered under warrantee.
On average between 80,000-100,000 miles the average person spends an adittional $500. So if you've financed that $1,345 warrantee then you've thrown away about $2,000!
