I thought I would let anyone know who does not have access to a store selling the Flash Car System...
For the fun of it, I thought I would try the Mr Clean Auto-Dry System that WalMart sells. (It was less than $30.00 for the kit) Believe it or not...it WORKS! Now I don't have access to the Flash system for a side-by-side comparison, but I'll be darned if it didn't leave my car clean with NO water spots or streaks! So if you don't have a way of buying the Flash Car System, give the Auto-Dry system from Mr. Clean a try.
I'm not totally insane...I tried it out on my Intrepid BEFORE I used it on our MINI.

Total time for both cars: 1 hour. Not bad.
