2018 Chevy ZR2
Just like the days of Mini Vans. Mini Vans are going extinct as well.First, cars are pretty much dead, few people are buying. The wave of crossover SUVs has all but wiped out the car market. Go to Chevy's website and pull up the vehicle choices: They list SUVs, Trucks, EVs, Cars, Performance
The Corvette is an outlier, a performance vehicle. The Camaro is listed there, but I thought they had discontinued it.
In SUVs, I agree, it seems like the SUVs overlap so much in size, etc. I would think they could consolidate the group of Trax, Trailblazer, Equinox, Blazer and Traverse could be compressed down to maybe 3 vehicles, and then a new vehicle in between those crossovers and the Tahoe would be a good fit.
If you look at the SUVs that Chevy has, there is just over a $13K spread between the Trax and the Blazer starting MSRP (Traverse is slightly under the Blazer?) and then almost a $20K jump to the Tahoe MSRP. A $40K Body on Frame SUV based off the Colorado would fit nicely in that gap.
