Looks good at first glance;
1. Tranny rebuilt and still under warranty? Could potentially be good.
2. Miles are pretty low for a 92... not bad.
3. The '97 style grill looks nice... not so sure about the corner trim though
3. Pearlys are purty...
Now, my knee-jerk reaction though contains a lot of caveats and unanswered questions;
1. Was the tranny rebuilt by a reputable shop? Is the warranty even worth the paper it's written on?
2. The seller got some information wrong: 260hp??? Please! LSI? It was an LSL in '92... don't think there WAS an LSi
3. Rear wheels are on backwards
4. Antenna's sticking and will probably need lubed/replaced at the earliest convenience.
5. Leather's worn... but looks decent.
6. Looking at the seller's history, looks like he/she sells quite a variety of stuff. This usually means a private seller. However, the thing that strikes me wrong about this is that a private seller should know more about their own vehicle, especially since the grille strikes me as being an enthusiast thing. Maybe that's just me being a little too paranoid... but this seems to be someone who's bought the car relatively recently in order to sell.
Just my 2c
