The Volkswagon comes with CC01 Chassis, which is the same as Hard shell Pajeros, Soft shell Pajeros, CRV, Jeep and MU.
It's not for "Fast play" but the truck looks very real while running.
I suggest not to put anything faster than "black pig" because the cooling for motor is terriable in that chassis. Plus parts are getting very hard to find too..... If you want, you can give the Hummer with TA01 chassis a try which gives you the same realistic look but you can put in a faster motor...
They both run about the same price......
