Not to rub salt in any wounds or anything, but it's always a good idea to "baseline" any car that you buy....ESPECIALLY (and I know this sounds crazy, esp a "certified" used car, but...) a car from a stealer..er...dealership.
Remember, their #1 goal is to make profit.
The more they have to spend on the car to make it right, the less profit they make.
Stealerships are masters at dodging the important things, and overlooking them, sticking the buyer with the costs to do what they SHOULD have done in the first place.
Case in point, I was at CarMax awhile back, and happened to notice a Honda Odyssey (fairly new) that had nearly bald tires on it (all 4 actually). WTF?
There is a REASON dealerships charge "dealer retail" and it's SUPPOSED to be for a fully reconditioned vehicle that doesn't need anything.
Again, they will side step this every time to save a few bucks.
In a perfect world (or at least a more honest one) people would be responsible and accountable, making sure things were done properly in the first place, but because we live in a greedy society....
It is OUR job as consumers to check everything and not let them get away with it!
****Interesting side note**** I was looking at an '06 G35 6MT sedan at carmax some time ago (might have been the same time I noticed that Odyssey, not sure), anyway......
after I had taken a test drive and before making any commitments to buying the car, I told the guy I wanted to have the car checked out by an Infiniti dealer (who just happened to be right across the street, literally) before making any decisions.
He informed me that this was unnecessary as they do a thorough inspection and that they have a wonderful "7 day return policy" and if I'm unhappy to simply bring the car back. That is fine, but I still wanted it checked out first (something I do before I buy any car). He said not necessary again. I said "see you later".
Oops, sorry OP for the rant there...lol.
