It's really according to the reliability of the car. In my case I bought a Dodge van and they come with many bells and whistles, which means there are a lot of moving parts. Plus there are many electrical parts these days. They all can break.
I went with the extended warranty and have been glad I did many times. I've had it 4 yrs and I intend to have it 4 more. (one more kid through college moving) its paid for itself and with 3 more yrs of it I ought to make money.
It is important to note that they do negotiate the price of the warranties.
We got a lower price on a longer package and didn't pay taxes on it.
Try to be realistic on how long you plan to keep the car and the estimated mileage over that period of time. We drive about 12,000 miles a yr.
I've never heard of gap protection but I think it's a rip off.
You can also negotiate the upholstery treatments and scratch and dent protection. If you are the kind that won't take it in for these things, don't pay top dollar. We negotiated down to half those costs from $300 to 150. I drive them crazy bringing it in for every little thing but I have a clean van and have gotten my money's worth!
Good luck!
