Wife got a new Toyota Starlet in 1997, we took out the factory extended warranty which took it out to 8 years, cost about $500 back then, about 3 months before it expired the car blew a rear seal which was a major repair as the engine/gearbox had to be removed and dismantled, under the terms of the warranty we had to pay for the new oil but not the $2000 repair.
We now haqve Hyundais which come with 7 year unlimited warranties.
I think the difference is a manufacturers extended warranty vs an aftermarket warranty which we have all sorts of horror stories about.
