Thats good. You are an informed consumer. I cant count how many times I've heard horror stories from folks who have bought used vehicles with guarantees that it was 1) never in an accident, 2) had all recalls performed, 3) owned by a little old lady who hardly ever drove it, 4) Transmission/engine, etc has been rebuilt, and come to find out none is true. Our DJ is still covered by the factory bumper to bumper, plus we purchased a 7 year 100k bumper to bumper on top of that. I, again, feel confident about this purchase from Carmax. Until they screw me over, I will continue to use them. Who knows, maybe they are baiting me. On a side note, I would not use them to purchase a truly "used" vehicle. We have only purchased ones that are 1-2 years old and have low mileage. I use craigslist if I'm looking for an older, higher mileage "beater" vehicle, knowing that I will have to do some sort of repairs, catch-up maintenance on my own.
