Faults:

Water pump went out at about 80 thousand miles.

Car needed a new muffler about every two years.

General Comments:

We bought our new mocha brown '78 DL 4 door in may of 78.

The Concord was the best American car I have owned.

It started every time.

It drove smoothly, even when it had over 100 thousand miles.

It was our first and last AMC car. When it was time to buy another new car, AMC was gone.

Faults:

The plastic valve cover was a chronic leaker until replaced with a new design with thicker cork gasket (after-market dealer fix).

General Comments:

I ordered this white 4 door sedan new from the factory to my spec, with 5 speed, manual steering, and blue broadcloth interior.

I drove it for a decade daily commutes, camping, desert drive-abouts. It had very low numerical axle ratio, plus the overdrive fifth gave final drive under 2:1, which yielded 26-28 mpg on the highway if kept under 70mph.

These were the last of the 2WD's from American Motors, althouth the 4WD eagles were made til '88.

I loved the car and would buy another in a heartbeat. At about 200,000 miles, it gradually became even more of a slow turning/high torque at low engine speeds character. I could not spin the engine over about 3000 rpm and it chugged like a diesel. Eventually on a 2500 mile trip it pulled 34 mpg (!) but I noticed a timing chain noise. Replaced the chain, which recovered the correct valve timing and original character. I had removed the catalytic converter, air pump, etc earlier, which no doubt helped gas mileage also.

This engine never had the head off --- only replacing several water pumps plus an alternator.

I gave it to eldest son at about 250k miles and he drove it until CA motor vehicle insisted he replace the converter etc removed, which was prohibitive costwise.

When he junked the car in '96, it still ran good with approaching 300k. The vehicle had a lot of galvanized panels and never showed any rust.

I now drive a cherry '82 Eagle wagon with almost 200k miles.

Long live the memory of American Motors and the other innovative "independent" forebears of Nash, Hudson, Packard, and Studebaker!!
