Volvo built the iconic, brick-shaped 240 from 1974 through 1993, and the only way to get more sensible than a 240 sedan, back then, was to get the 240 station wagon. 240 wagon owners love their cars, and plenty of them have managed to stay on the road to the present day. Today's Junkyard Treasure is a well-worn early example, found in a Denver-area car graveyard last week.
Volvo changed the naming terminology for the 200-series car family over the decades. Through 1979, the second digit in the three-numeral name (in North America) indicated the number of cylinders and the third digit represented the number of doors. After that, these cars were all badged as 240s or 260s, but most Volvo lovers still call the coupes 242s, the sedans 244s, and the wagons 245s, regardless of year of manufacture. The DL trim level was the cheapest one in 1979.
This one got just past the 200,000-mile mark during its 42-year career. I find many 240s (and 260s) in wrecking yards, and nearly all of them show at least 200k on the clock.
The Lambda Sond grille badge means that the car has an oxygen-sensor-based feedback system on an electronic fuel-injection rig, which has been everyday stuff since the late 1980s but was still pretty futuristic in the late 1970s.
The four-speed manual transmission was a bit dated by 1979, though Americans could buy four-on-the-floor-equipped new cars all the way through 1996. This car has the optional electrically controlled overdrive, with switch on the shift knob.
