If the production vehicle matches the concept vehicle it would be awesome, but they rarely do. The bean counters usually remove the coolest features/capabilities.
i also think GM has lost the Offroad crowd. GM has zero credibility in the market segment. They abandoned an iconic brand, not only stranded a huge segment of their off road market but screwed them over with the whole sell, shut down, sell shutdown debacle. GM should start with a $10,000 discount for any former Hummer owner that wants one.
GM sees Ford selling $60,000 Raptors as fast as they can make them and Jeep dominating an entire market segment. Now they want to jump back in. Tread carefully. GM also needs to start paying attention to their safety warranty concerns with current Hummer owners, ie stepping up on air bag deployment issues.
i would live to see this happen but only if GM is willing to do it right, stand behind it and mend some fences with Current/former Hummer owners.
