How would you have it if you controled GM\'s lineup?

I would do it like this:
Buick would have only hybrid, fuel cell, Battery electric, and alternative fuel ICE powered vehicles. Their models would consist of Regal (midsized), Lacrosse (fullsized), Skylark/Riviera (muscular 5 door coupe/muscular3 door coupe), Excelle (supermini), Verano (compact), Encore (subcompact), Encore GX (subcompact crossover), Enclave (compact-midsized crossover), Enclave XL (midsized-fullsized crossover), GL6 (compact minivan), GL8 (minivan). Buick would be focused on the chinese market, but would still export some to the USA. Chevrolet would take hold in north america. The Chevy lineup would consist of, Blazer (solid axles, removable top, fullsized 4 door SUV), Trailblazer (rwd/awd midsized crossover), Trailblazer XL (rwd/awd fullsized crossover), Suburban (irs/ifs fullsized SUV), 1500/3500/2500 (fullsized pickup), CHEVELL-E (electric 2 door muscle car styleed after 69 chevele), Camaro (3 door fastback ponycar), impala (fullsized-midsized rwd sedan), Astro (small cargo van/minivan), Express (Large cargo van/passenger van), S10 (south american transverse compact pickup, imported to US maybe), Colorado (midsized pickup). The Impala’s trims would be 3.0TT base and more premium Caprice, 425hp Sport350 and Caprice S, 460hp Ultra luxo Caprice LT, 630hp SS427. The 15/25/3500 series trims would be W, scottsdale, custom, scottsdale LT, high country, chyenne, and silverado SS427. the camaro needs a better interior, and a more simle trim lineup, as in 2.7t base, 2.5 hybrid LT with better interior, suspension, and a decklid spoiler, sport350 425hp, SS396 530hp, Z/28 5.7 570hp, rollcage, track rubber and seats, big wing, 800+hp ZL1 withy 67 vette hood scoop. To cover the small car segment I thought of bringing back saturn with sonic, cruze, spark, equinox, trax, and malibu based offerings. Caddy would get a ciel based eldorado, CT5 seville, ct6 fleetwood, ct4 hybrid, esv only escalade, electric XT4, and trailblazer based XT6. The V models would be callede blackwing instead. GMC would have luxury electric truck/SUV/Van offerings. Saturn would be the main company in South America, with chevy badged S10s, vans, and fleet cars. Corvette trims would be 396, 427 (with 67 scoop), track monster Gran Sport, and AWD twin turbo flat plane crank Z06
