Welcome to the forum, Michael.
Make sure you look it over thoroughly for rust. Look at the rear frame rails ahead of the bumper mounts. Check out the floor underneath...you won't be able to pull up the carpeting while it's still in the owners possession, but you can get a general idea from underneath.
Look under the doors, the fenders, rocker panels, quarter panels, etc. The car looks pretty good and original, but how many Minnesota winters has it endured? Unless it was sheltered over the years.
The price isn't bad..just make sure the car is somewhat solid. Mechanicals can always be upgraded.
If you're lacking in mechanical skills, you can always learn from experience and books...never underestimate the power of books.
Good luck! Let us know how you make out.
