According to Kelley Blue Book, auction prices for Volkswagen’s diesels cars are dropping faster than similar models that are powered by gasoline.

According to auction data gathered before and after news broke that Volkswagen had admitted to federal investigators that their cars illegally polluted, prices for Volkswagen diesel cars dropped 16 percent. Prices for Volkswagen gasoline cars only dipped 2.9 percent over the same period.

According to the car industry site, interest on the Volkswagen diesel models has only declined 2.4 percent.

Shortly after the diesel scandal broke, discount hunters roamed lots looking for deals on diesel equipped models.

Recent data could show that the clouds have finally gathered and could be there for a while.

According to KBB.com, Golf and Golf Sportwagen were hardest hit among Volkswagen diesel shoppers. Interest in those cars waned 3.7 and 6.2 percent respectively.

Conversely, interest in the Audi A3 and Volkswagen Jetta Sportwagen have increased by 1.6 percent and 3 percent respectively. The website reported that the increased activity is reflective of overall interest in the segment.

Audi A3 shoppers were most likely to cross-shop that car with the Lexus NX, Mercedes-Benz CLA and BMW 2 Series, which don’t offer diesel engines in the U.S. A spokesman for KBB said that shoppers interested in Jetta TDI models didn’t necessarily shop other fuel-efficient models either.
