We were going to take out a extended warranty on our 2008. smart only offered a a 2 year warranty when the car was new. It was pricey from the factory. Still have the paper work. Decided not. Maybe should have. Later on, in the smarts life. The clutch actuator died. Had to replace, a second heater blower motor. The cost, of both those items, basically would have been the same price of the extended warranty. So it didn’t matter.
We bought a new Honda Fit 2 years ago. Extended factory warranty, from Honda 700 bucks. 8 year 80,000 miles. Covers everything. Bumper to bumper. The navigation screen, in the vehicle replaced. $1,700 bucks. Rear LED tail lamps,are $240, a piece. CVT transmmision $4K. In today’s world, the new cars are so complex. It makes sense to have a extended warranty. If you plan to keep the vehicle for a while.
Read carefully the fine print on these warranties. Check the deductible. Good Luck.
