My fam has bought three rigs from them... two Mavericks and a Wildcat. The Mav's were purchased completely factory but the Wildcat was built by SDR as part of a build-off but Bert's does have an in-house shop, Bert's UTV, and SDR does build a lot of their custom cars as well as Desertworks. I believe they hold on to the spare's for people who come in wanting OEM parts. Picture of my dad's rig is attached aka "SAVAGE".Bert's doesn't do the builds themselves. I'm pretty sure SDR does most of thier stuff for them.
Yeah, they call it "Sub-Zero" - I was checking that out on Fri... Super nice. Awesome rear end setup with fuel cell. Here's pics for everyone... And, correction on the price! 49k!!!!! Almost 50... You can build a LS rail for that much, that will pump 500 horse.SDR and Desertworks do the builds. I think there maybe a third one they use too.
They had a blue and white Max with really cool aluminum work and cage. It was almost 40k!
