GM and Ford both are seriously cutting back on the rental fleet sales that pretty much have kept them alive the last half-decade.In May in the United States "GM dealers delivered 375,682 vehicles, up 4.7 percent compared with year-ago monthly sales." Key words are "GM dealers ... delivered,"

Iin the mid-crossover segment beside the, cough, 415-percent jump, GM touts the Pontiac G6, Saturn Aura and Chevrolet Impala as showing a 31 percent increase in the mid-car segment. For these sedans the GM lots are full of two-year-old Tahoes traded in, in May y about Chevy selling 35,665 front-drive Impalas, up 44.7 percent. This is what has GM rethinking a switch to RWD for '10, not harsher CAFE standards.
