The main sales guy is Dan (formerly of Highmark & Customweld). He is a good guy. As I understand it, Redline is a pool of toys (boats, sleds, rv's, atvs, utvs, etc) that you go in and buy into. The greater your purchase, the more time you get with the toys. There is an initial "buy-in" and then a monthly fee. It looks to me like if you were already making payments on a few toys, this could be a killer deal because you could get access to lots of cool stuff for basically the same monthly payment and you would have summer toys to play with for the same price instead of paying for a mothballed sled all summer.
I think the downsides would be that the units are all basically stock and other people would be using them "in their own way".
If my toys weren't all paid for and I needed to use the latest and greatest, it seems like it would be a pretty smart way to go.
