That is some excellent advice for my type of riding. The basic 64" X3 has always been reasonably priced through the years. And it's still a turbo, great for the dunes. Sometimes I confuse myself with the offbeat models and offerings, but there have been several times when I think to myself something like "DUH!....there is a REASON why everyone bought X3's when they first came out, and continued to buy them!".
Regarding my OG Maverick which I sold in April, it served my personality well, because I had no problem hanging out in the small dunes or staying on the outer perimeter or driving through valleys. At Superstition Mountain west of Brawley, I drove it more aggressively. And in the desert it served my need for speed, because I actually am a very crazy driver outside of the dunes. At 4 Peaks and Queen Valley usually no one ever passed me going up, and I guarantee that no one ever passed me going down. I passed many, many vehicles, including X3 4-seaters. I'm thankful (and probably very lucky) that I never crashed that thing, not even a broken front end arm or spindle, only 2 belts broken at Glamis.
