They do a lot of amateur rally in the forest behind my house and the standard big money cars rock up (Scoobies, Evos, Escort Mk1s/Mk2s, Cosworths, etc.), but the lower leagues tend to be Various hatchbacks, Fiesta, 106, 205, Focus, Corsa, Ka, Escort Mk5/6 RS2000 FWD and AWD, plus everything in-between, even had a TDi this year. If it had wheels, they ran it. But none of them were daily cars for a reason. The damage they suffered just from a day in Cropton Forest was unbelievable. 5 cars were written off (zero chance of repair), a handful suffered punctures to the floor thanks to massive rocks getting kicked up. Plus various amounts of shunt damage from going off the road.
You could turn a daily driver into a track slag and still use it on the road. But in the world of Rally, you need a dedicated car. Purely because of the environment, what flies at the track will not pass the scrutineers at a rally. Even at amateur levels like the events held round here, it costs a small fortune to participate. Sure the cars all had to be road legal (rules of rally), but none of them were cars you'd actually want to drive on the road.
