Carchex is another good option that is through the same company as Carfax and well reviewed and offers a cheaper option. I paid 2500 for a 3 year 60k mile warranty--that was their best one covering everything except brake pads/disks and squeaks and rattles.

I asked for a quote before I got the warranty for a simple 18 dollar regulator switch repair in the A/C system and it was 600 bucks with labor to get at it and replace it. So not worth it to go without a warranty on these cars.

especially with a 535--wayyy too many parts on that engine alone to worry you
