Great concept and I would like to see some additional parts coming to the market for the Colorado!
With that said, someone mentioned the lack of currently available parts and while the aftermarket isn't anything like what you can find off the shelf for a JK or Tacoma, - there are already some nice parts available from some great fabricators and companies. A few examples... 589 fab has a great low profile bumper and winch mount, SuperSkidz has some solid looking plates, the factory sliders are not half bad, King and Fox have some quality shocks ready to go, Icon has a mid-travel setup, and Baja Kits/Brenthal have a really, really nice long travel setup.
If Eaton or GM would sell the factory lockers, I would be very tempted to build a diesel Colorado with a Baja Kits kit.
Back to the AEV concept though, it is great to see the interest in the vehicle and I hope that AEV brings some new parts to the market.
