At first blush, a 139,000-mile, 1981 Mustang selling for $3,500 bucks isn’t a terrible deal. It’s relatively low mileage for a car of that vintage.
Even if it is a four-banger, there is plenty of potential in such a machine if it is in good shape. Therein likes the rub with this freakish Fox that we ran across for sale on Facebook marketplace out of Portland, Oregon.
While the ’79-’93 Mustangs are so flexible that you can turn them into any kind of performance machine, pushing some envelopes might make such a car difficult to sell down the road. By all means, you should mod a car however you want to, but just don’t expect potential buyers to come clamoring if you stray too far off the beaten path.
