That's a lot of "insurance" to pay on a $21,000 car (even loaded up with the technology package and other options it's hard to top out $24,000).
Electronics are expensive to fix but I'd rather put that $2,400 in the bank and earmark it for potential repairs. Then if you don't use it, it'll be there for applying to the next car purchase.
Too much can happen in ten years. Some kid may steal your keys and destroy your car next week and you won't get the extended warranty money back. And the warranty companies seem to always find a way to find all kinds of exclusions to avoid having to pay any claims.
So I'd cancel if it were me. Some people like having "peace of mind" though.
And try to avoid curbs and potholes. :-)
Enjoy the new ride!
