It is really difficult to choose the best kit car from '90's because competition was great at that time. Many manufacturers found interesting to compete in F2 championship which were 2 liters front wheel drive cars.
Some of them are: Peugeot, Seat, Renault, Citroen, Hyundai...
Peugeot, Seat and Citroen were the best from what I remember and I remember very good almost everything about this sport.
Renault Megane Maxi or kit car came little bit later then others but it was very powerful with around 300bhp and beautiful noise of the engine which revved up to 9000rpm or more.
Most of the works drivers were from France: Jean Ragnotti, Phillip Bugalski etc.
Watch this piece of rallying history and enjoy...
