Changes on the dot-com front since last year's NADA convention:
Third-party buying service Greenlight.com is being acquired by rival CarsDirect.com.
Internet auto broker CarOrder.com has become CarOrder Inc., which owns two dealerships and aspires to become a dealership chain.
Buying site AutoMallUSA.com changed its name to Vehix.com, and autodealerjobs.com now is autojobs.com. Both were exhibitors last year.
