My 8 and 11y old daughters love playing it. They really don't mind the old card design. We also built a "circuit" with cardboard where we use my old micro machines cars to visualize our trip.
We also play with our own rules where there is no need to find a greenlight after reparing/changing wheel/refueling the car. Otherwise it is always the player getting the 'véhicule prioritaire' (aka firefighters card) who win and it spoils the fun.
