Looking for my Dad's '73 Roadrunner.
H code 340
GK6 Autumn Bronze Metallic
Tan interior with bucket seats and console
727 with slapstick shifter
Black stripes
Painted mirrors
A Bose 1401 sound system with speakers on the package tray
15in slot mags with 60 series tires
Date and location:
It was in Montgomery county, Maryland around Germantown/Gaithersburg.
(possibly Bethesda but most likely not)
Both pictures are from September 9th 1983 taken for the purpose of listing it for sale.
Registration information:
License plate was GRG 700
My Dad's name is Mark and would have been 21 at the time
Sale information:
A younger teen was trying to buy it and left to scrape up some money, but before he got back someone else had approached Dad and bought it with cash and he couldn't refuse even though he liked the kid before because he needed the money.
It wasn't much, I think it sold for $2500 or $1500.


Blurred out my sisters faces, I'm not there because I wasn't born yet.
Any info would be appreciated, I'd like to buy this car someday if I can track it down.
Maybe someone knows something (or owns/owned it!) as it is a relatively rare car with a interesting color combo.
Possible sighting 10-15 years ago in Germantown/Gaithersburg MD, so I have hope that it's still around somewhere...
There's also a small chance it could be this '73 Roadrunner drag car that is in the area, but I doubt it because the drag car has black interior and my Dad's car had a tan interior but you never know.
I'd have to look at the fender tag and vin.

Are you sure it was a 340 car?

There's no engine size decal on the sides of the hood bulge.

He remembers clearly that it was a 340 car.
(might have been a built 318 that he thought was a 318, but I really doubt it.
It was his daily driver for a few years, and he used to work on Mopars all the time.

Looks like original paint and stripes.

No engine size decal was put on 318 cars.

All others got one- 340/400/440 (and 360 in '74)
