The del Sol was first sold in the United States in two versions: the S and the Si. The S was the base model, and it came with a 1.5 liter SOHC engine and 13 inch wheels. The Si model came with a 1.6 liter VTEC engine and 14 inch wheels.
In 1994, the VTEC became a trim level on this car. That model got a DOHC VTEC B-series engine making 160 horsepower. It was the same engine used in the Civic Si-R.
Less than 75,000 of these cars were sold in the US during the 5 years it was sold here. That puts the del Sol somewhere between rare and common. They are popular with the import car modding crowd, a culture that was still in its infancy
while this car was being produced.
If you are trying to find one of these to buy, try looking in your local car classifieds. If that fails, try ebay. It's also a good place to list your used car if you need some cash to buy or restore your del Sol.
