GM is revamping efforts to sell luxury Cadillac automobiles in the Japanese market, according to Asia Pulse.

With 2007 models being introduced starting in February, the automaker is increasing the number of sport utility vehicles with Right-Hand Drive.

The carmaker does not believe it can grow sales of vehicles such as the SRX if it only offers vehicles in Left-Hand Drive spec.

GM is also working to strengthen its after-sales service, the report added.

It will distribute coupons to customers who buy a 2007 Cadillac this year. The coupons can be redeemed when the vehicle receives basic maintenance, such as its first vehicle inspection in three years.

The automaker sold 972 Cadillacs in Japan in 2006, 17% fewer than in 2005.
