Dual batts suggests winter pkg, but check the back door, RHS for an orange/yellow sticker. It says the equivalent of winter package (but not in a language you'll likely understand <img src="/forums/images/graemlins/lol.gif" alt="" /> ).

As far as LSD, you're looking for another orange sticker, driver's doorjamb. OR a little switch that says something like r.diff, or RDL, etc (likely next to the aux 12v scoket, low in the center stack).

$7500? Pretty good, esp if it has the timing belt done (due at 100k).
