Welcome to the forum, you have come ro the right place. Are you familiar with vehicle maintenance and have a good tool set? Even doing a lot of your own work, a vehicle that old will absorb a lot of time and cash.
It will need tires if they are over 6 or 7 years old, check the date code. A blowout at highway speed will really ruin your day. Brakes, steering, suspension, and drive line need to be inspected by an experienced eye, grease is likely dry from lack of maintenance. Stuff breaks so be forewarned.
The 440 and 727 transmission were excellent units in their day but gas mileage was not a strong point. The automatic choke system was problematic, the crossover heat passage in the intake manifold is likely plugged with carbon and the heat riser valve likely seized. I honestly suggest keeping your money in your wallet until you can afford something much newer.
