If you don’t already know, Omaze is a stellar online fundraising platform that offers once-in-a-lifetime experiences to support a range of nonprofits. Dream vacations, red carpet premieres, restored vintage cars can all be won through Omaze while supporting a good cause. In this instance, Omaze has teamed up with HIMALAYA, the custom-build garage that creates one-of-a-kind Land Rover Defenders down in South Carolina. The duo is offering a chance to win an unbelievable grand prize: a beautifully restored, fully customized Land Rover Defender 110 — taxes and shipping costs included. Plus, every donation for the chance to win supports the National Geographic Society and their work using the power of science, exploration and education to protect the wonders of our world. We took a peek at a few of the top-line customization options available to the winner, and we’ve gotta say, this is one shot you don’t want to sleep on.

1. Custom All the Way: HIMALAYA’s very existence is in the spirit of sweating the small stuff, with customization options going way down into the nitty-gritty. Whoever is lucky enough to win its campaign with Omaze build will wind up with a custom-made chassis, a V8 engine conversion and much more.

2. The Finer Things in Life: The Defender will always be a fundamentally rugged vehicle, just rearing to go all-out off-road—but they also clean up pretty well. HIMALAYA will outfit the winner’s Defender with a high-quality leather interior, a full-spectrum paint job in a custom color scheme and a state-of-the-art sound system to boot.

3. Hitting the Road: Omaze is making sure all future adventures in the custom Land Rover D110 are as extreme as you’d want. They’ve added $20,000 to spend on gas money for the foreseeable future or anything else you’d like—like, I don’t know, a duffel bag full of cash to keep the passenger seat warm.
