After completing the Wasted Garage mission you have the opportunity to steal a Wasted themed ATV from some bandits as you exit the garage.

This ATV is different (and cooler) than the normal ATV that you get from Dan. The Wasted ATV has a skull for handle bars and wheel spikes.

It is possible to have both the normal and Wasted ATV parked at the Haggar base. But when you complete the Wellspring mission to get a garage to store your cars, only the normal Jetter ATV is available in the garage. If you try to go back to where you last left the Wasted ATV it will be deleted.

I would like to continue to have access to the Wasted ATV after the Wellspring garage is unlocked. Either as a separate vehicle or as a theme/skin for the normal Jetter ATV (just like the skins you can buy for the other cars).
