- While there are positives to
purchasing coverage through an independent warranty provider, you’ll also find downsides. Neither third-party providers nor CarMax warranty options guarantee the use of an automaker’s genuine car parts or certified dealer technicians when repairs are needed.

That aspect alone makes this warranty for anything more than a basic car something I would not want. Rather put the $2100 in an ETF and pull the money when you need it. Odds over multiple car ownerships of Toyota's is that you are ahead of yourself. The only reason IMO to get a warranty is if you cannot afford the repair cost, i.e. have zero savings. In that case I suggest you better buy a Toyota Yaris and figure out how to make more money.
