If you want it, buy it. With that kind of (low) mileage, there is little risk involved. Offer $11,000. - and go from there. You should be able to get this particular Mustang (which looks very nice) for no more than $11,500.

As for having some sort of absolute guarantee of reliability, that isn't completely possible with any car - but you can always invest in an expensive, overpriced 'extended warranty' if you are all that nervous about buying this two-year-old, six-cylinder Mustang. The CarFax report is a good guide (but not infallible, as you know) and if the Mustang actually has only 13,000 miles, it's hardly broken in.

Another factor to consider: a 6 cylinder Mustang is usually not bought to race or beat on. Quite possibly the previous owner was female and traded the car for more space, better gas mileage or because she really wanted an SUV. Maybe a young couple had a baby and needed a bigger car or perhaps the previous owner couldn't afford the payments any longer. I doubt it was traded because it was a 'lemon' - but ask for any available service records for the car and see what you get, if anything. Meanwhile, decide if you want the car or not and make the dealer an offer - or keep looking.

Good luck.
