known for bad brakes and weak gearbox's and need to be kept serviced or the bottom ends can let go due to oil clogs. There good cars and are true pocket rockets, comfortable and handle. Just dont do any hard launches or go over 1 bar on a standard car or the pistons will melt. Plus make sure its got a front mount and got rid of the interheater that sits on top. they arent undersealed either as the mainly imports so worth doing too
