The new 2015 3 liter diesel, such as in the Touareg, Audi A8 & Q7 and Porsche Cayenne is still not available for sale or lease. Although I have read in the dealer magazine "Automotive News" that Porsche intends to sell their new inventory of 2015 Cayenne Diesels as "Used" in the near future.
My local VW dealership called me up several times because I was looking at continuing with a new lease on a 2015 TDi. I was expecting some great deal, however this dealership and some others shrewdly took a waiting list for this day and are aware of the profit making potential in this situation.The dealership says that VW is offering $5k off of purchases and with great financing or $8k of of a leased car, that sounds pretty good to me. The part where they lost my interest is that they wanted to add a $3k dealer markup. I told them that my 2014 looks like a keeper.
It's worth mentioning that there are soon going to be other diesel car choices available. Mazda has long teased us with offering a diesel option and they are suppose to introduce their small suv with a diesel option this year. Chevrolet will offer the Cruze and their small suv with a diesel option as well. Landrover and Jaguar are selling their diesel suvs and BMW and Mercedes is offering their options as well, with some exceptions.
