I don't think the car is in AZ.
The rust area in the A pillars seems like an odd place. If the rust is in the same place on both sides, any chance the top was spliced? The drip rail line looks straight but I don't why it would rust there and not in the bottom corners.
For a good price, go for it....and swap me the LSD tranny.
Where are the 6s and 8s? Discount $1K for not having the correct wheels.
