Collectibility

The 2-seat AMX is the most widely collected car built by AMC. The 390 V-8 engine is the most common and by far the most desirable. Some collectors favor the 4-speed over the automatic. Because all later AMC V-8's were externally interchangeable, it is not difficult to install the 390 in an AMX originally built with a 290 or 343; if equipped with an automatic, the heavy-duty Borg-Warner M-12 should be installed in place of the M-11 used with the smaller engines. Because AMC didn't match numbers on engines and bodies, switching engines generally doesn't decrease the car's value to collectors. Valuable options include factory air, which is quite rare, and the "Go Package".

Many collectors believe that the changes made in the last year of production, particularly to the suspension, make the rare 1970 AMX the best, but some actually prefer the antiquated suspension setup on the earlier cars. 1970 models command a small price premium over the earlier cars, but for most AMX fans it's primarily a matter of personal taste.

Because the AMX was produced in very limited numbers and most of them have been run into the ground, well-optioned, low-mileage examples are extremely rare. AMXs in fine-to-excellent condition typically sell for upwards of $9500, but restorable AMXs in good running condition can be found for well under $4000. Be wary of rust (always a problem with older AMC cars) and poor-quality replacement parts.
