GM or not, it would still be an interesting tour!
I worked for GM Hydra-matic for 34 years I'm a car guy and presently restoring a model T. You will love the Heritage Museum plenty of cars and info
Too many concepts and maybes... at least ford did the "T"
On an OT and sad note, the Walter P. Chrysler museum is closing for good the end of this year.
With all the automotive history in America, one would think there would be other museums willing and able to take on the Chrysler exhibit. 'Gilmore' pops into mind...
