Yeah the ST185's are the 5th gens. Check out
www.allwheelmotion, www.alltrac.net or
www.gtfour.com Tons of info on those sites and GTFour.com also has a buyers guide too. I'll likely be getting an ST185 very soon too. They're very robust and the engine is a beast. They're kinda heavy, but you can strip some useless weight out plus mods aren't too expensive. Good luck and hope this helps.:alien:
