i maintain one mugen buggy. Thats it. But i have parts for a couple of them and several motors, boddies. I also have a good amount of after market parts. It cost alot to keep it in top shape all the time. when i do get a truggy, darn straight it will be a mugen. I mean i have a TON of the parts.
As far as another buggy and extra cars does not make sense to me. I mean, you can only drive one at a time. I like to think of it like college basketball, one great player can take you all the way. Why? because there is only one basketball.
sorry eerrr rambling and such.
