As to a "higher" level name look no further than the Taurus example above. Went from a low to low medium priced car for twenty plus years to the car we have now which starts at high medium price. With the change to domestic production, upsizing, and with a model with performance overtones, Chevrolet has a chance to transform the image associated with the name Aveo. I see no need, at this point, when logos, medallions, literature, signage, etc. have already presumably been started in the works for GM to shoot themselves in the foot with an unnecessary name switch and with the resultant costs that would come with it. Instead, go on a massive advertising mission emphasizing the move up the ladder the Aveo is making and point out the domestic plant revitalized just to produce it here in the States. The first implication is that the Aveo has come a long way, The second is that it's as American as baseball. The third is that much needed jobs , if not having been created, at least are preserved with bringing the brand home to the U.S. Great public relations and it puts the car square in the public eye which will bite into all the fanfare surrounding the Mexican built Fiesta and the Italian ( or Polish, and for US bound versions- Mexican ) built Fiat 500 ( although arguably that car is in Sparky territory marketwise ). By sticking with the name, if Chevy markets the loyalty angle right, they are showing a commitment to developing quality and local content. Potential customers will lap that up.arrghhh- plunder the buying public booty maties!
