there is logic to why they are keeping Chevy,Buick and caddy lines and dumping Pontiac ,Saturn car lines.
to keep the Government Happy.
Chevy competes with Pontiac on performance autos . the vet and camero name plates.
and the Saturn competes with Chevy on younger and smaller car buyers.
also they dumped olds some years back because it competed with the Buick for older & middle age driver pubic. it was just what brand name sold more units for a 2 year study. and olds lost.
caddy there keeping to get upper class car buyer and not let Ford have the market all to them self with the Lincoln car line .
