I too have heard that Route 66 is rather touristy.
I regularly do US road trips.
Two years ago we did Houston>Dallas>Memphis>Nashville>Bowling Green>Lynchburg>New Orleans>Houston. Highlights included Gas Monkey Garage (Dallas), Graceland, Corvette plant, Jack Daniels Distllery and New Orleans' French Quarter.
Last year we did the West Coast: San Fran>Mammoth Lakes>Yosemite>Las Vegas>Grand Canyon>Palm Springs>Los Angeles>Santa Barbara>Carmel>Santa Cruz>San Fran.
This year we are doing: Chicago>Detroit>Columbus(OH)>Indianoplis>Chicago. Highlights will include a NASCAR race and a country music festival.
The first one we had a Camaro SS convertible, second one we had a BMW 328i and this time we've booked a Chevrolet Tahoe or similar. It's fun to try different cars. On the Pacific Coast Highway we actually stood out in our BMW amongst the Mustangs and Camaros.
If you're dead set on doing something in a Mustang I recommend the West Coast rather than trying to do Route 66. I think you may be disappointed if you try that. Also one way car rental fees can be high!
If you have any specific road trip questions please ask. I recommend setting yourself up a spreadsheet....
