Luxury car manufacturers are continuing to add items to pamper consumers and to attract customers.

One of the latest luxe items is the back-seat vanity mirror. Available on Mercedes-Benz S-Class models, some Audi A8 models, and the Cadillac DeVille DHS, the mirrors bear a close resemblance to the vanity mirrors in the front of the vehicle on the sun visor. These mirrors, however, are located in the ceiling in front of the rear seats and drop down.

While the mirror generally comes as part of the standard package, it may be included as part of an options package with a price tag of up to $2,000.

Also on the marketing front for luxury vehicles is the credit card rewards program.

Taking a cue from the airlines, in an effort to boost customer loyalty, more luxury-car brands are offering credit cards that allow customers to accumulate points which can then be exchanged for rebates on car purchases, leases or repairs.

At least 10 car makers are offering such cards in the U.S., according to press reports, including BMW, Mercedes-Benz, General Motors, and Toyota for its Lexus brand.
