Should I be concerned with the condition of these seats Update**

Usually good retailers can work wonders. This car looks like its been detailed, and still dirty arse seats.

Deal breaker for me.

But, seat covers are relatively cheap, or can even have them recovered for cheap (<$1000 for cloth, $1500-$2k leather). I even replaced my cloth seats in my Altima with Katzskin leather myself for $500.

That looks like flood damage to me.

Have you looked at the Carfax? Was it registered anywhere in the North East?
