According to a recent AutoWeek magazine article, vehicle buyers
are paying even more money for diesel options on used vehicles than
those engines originally cost new. For instance, the diesel option on
the 2005 Mercedes E320 CDI sedan was $1,000, but on the used market
buyers paid a $2,500 premium, according to the Black Book used-vehicle price guide.
The AutoWeek article concluded the reason is that consumers
want full-size vehicles with higher fuel mileage. It also estimated
that American buyers will purchase more than a half-million diesel
vehicles this year. Sales are expected to double by 2011.
Nearly every diesel-engine option is selling for more used than it did new, according to the Black Book data. This trend could ease as manufacturers put more diesels on the market.
