New lux­ury vehi­cles are expected to be cheaper in the com­ing months, due to increased incen­tives; but prices of used lux­ury vehi­cles are ris­ing, accord­ing to Bankrate.com. The role rever­sal is occur­ring because automak­ers are com­pet­ing for a smaller group of new-car buy­ers, and, on the other hand, the num­ber of used lux­ury cars avail­able is much smaller than the poten­tial buyers.
