The wildfire has improved my racing by around 2-3 laps over the mission. Which isn't too difficult. The guy who I bought it from bought a d07 and has been struggling with it to the point that he wanted to buy the d06 back!
I've never really been a fan of buggys, although some of the things people can do with them can be really quite fun. Hence why I have the t3 to play with. Can't take a touring car across a field!
