If you are planning to take I-90 thru SD, be sure and stop to see Mt Rushmore. There are several nice roads in the hills around Custer, Hill City, and Custer State Park you will want to drive,one, the Needles Highway is great, but with one car tunnels...be careful!

If you have a problem, the local Chrysler dealer has a Crossfire tech, although I have not used him since I owned my car in Texas; however, I have purchased numerous cars from them over the last 19 years, to include my wife's 09 Passat wagon, and my 09 VW CC. Service has always been great.

Enjoy the drive!
