I went to the local track I wanted to race at for a month or so and saw what cars were being run there. I started searching ebay for the car I decided to get that car happened to be a schumacher mi2. I found a GREAT deal on a used carpet run mi2 and purchased it off of ebay for less than half the price of a new kit. (this car is a tank as far a slamming the walls!)
I will agree that once you hone your driving skills and feel good you will probably want to upgrade your car as I did. The Schumacher mi3. I find it is a good idea to run a car that is ran at your local track as you WILL need spare parts that you don't have in your box. Trust me!
I also find support from the MFG. to be important and I am NOT bashing any company here but what I am saying is that Schumacher customer support is second to none.
Just my two cents. I hope it helped.
