Indeed.
GM's still got to add a whole bunch of squeaks, implement the interior design by Fisher Price, queu up a black model with a red pin stripe, add a couple feet of overhang, and be sure to get the engine up over the front axle, install one acre of unused dashboard plain, spray paint the plastic bits chrome, and route the dual exhaust into a single pipe then back out to dual.
Give em time, it takes them a long time to prepare one of their concept cars for GM production.
