4WD Cars with national/regional homologation

[Mirek]

You just answered Yourself. The cars are competitive only for a cup of same cars. But for something like that You need something very cheap and these cars are not cheap.

There is way better way for young talents to develop themselves. Take much cheaper R2 and go to proper competition in JERC. From there it's much easier to get into R5 than from some proto car.

There is different situation overseas but in Europe there is little sense in buying such car (except when there are very special rules made for them like in Spain).
