Looks like they replaced the right bench seat with a regular passenger seat and left a hole. That price is good. I would even be a little suspicious there was something else wrong at that price, but it was an SSV. How was the test drive? I have one a lot like it . It's fun, but has a few issues. The package says it has the Heavy Duty Aux Trans Oil Cooler. Is that not accurate?
And, the rear seat doesn't appear to be vinyl, either. But, oh, well. And, you're correct: it does have the trans cooler. Any out of the ordinary problems with yours? My biggest concern is never having owned a 4WD vehicle, I'm concerned with all the extra moving parts, (bearings, CV joints, etc.) That can get to be a lot of work or expense real quick. Gotta' go drive it yet. It's over an hour away and the dogs been sick. Never a dull moment!
