I have not driven a serpent buggy(although I do own a serpent truggy), but I did own a Durango and The 2010 Xray 808. I ended up selling the Durango. This is not to say the durango isnt a good choice, but the two buggies have completely different handling characteristics. For me the xray just does everything perfect, really the only car i have driven that just feel right. The car feels so planted, jumps well and is an absolute tank. Besides bearing failures I have never broke a single part. The Durango on the other hand to me was far to loose. The buggy has huge potential it accelerates like no other out steers any buggy i have ever driven and jumpes really well, but no matter what i did it felt like the rear end was on ice. best thing to do is to try a wheel each car and make your own mind.
