Mystery Car 90 was way too easy. This was none other than the infamous VW Rabbit—one of those cars that you’ve either owned or knew someone else who did. According to Greasecar.com, “The Volkswagen Rabbit (known as the Golf in Europe) was introduced in 1977 and was first offered with a 1.5L diesel engine. Production for the US market moved to Westmoreland PA in 1979 and the 1.5L engine was replaced with a 1.6L a few years later. In 1983 a turbo-diesel 1.6L option was offered.” So … it can be converted into a vegetable oil powered car!
At times, I thought about purchasing a convertible version of the Rabbit. It was a cute little car especially in red with a white top and a manual transmission. But the Rabbit wasn’t really built for looks. It was built because Japanese “econoboxes” were taking over the Beetle’s share of the market. See The Rabbit Archive for more details.
P.S. Did you know that the diesel model got 57 mpg on the highway?
