Here is a 1978 Mercury Grand Marquis that I bought in late October 2004. It has a 400 CID engine with 2-barrel Motorcraft carburetor, air conditioning, and 8-track player. Total cost including tax, title, and tags was $940.

Here is a picture of the engine compartment in Dec. 2004 or Jan. 2005:

Engine, Sept. '05

Engine compartment with new alternator, 9/4/05. The AC compressor clutch seized so I removed the belt going to it.

Valve cover.

Valve cover, 9/4/05. I intend to sometime install new spark plug wires as it is using some wires salvaged from other vehicles. The A/C magnetic clutch connector is disconnected.

Rear of car.

Rear of car, 9/4/05. The left turn signal/taillamp is a retrofit to meet standards for the state inspection as the original was broken when I bought it...I would eventually like to find an exact replacement lens but they are pretty scarce.
