Plenty do Russ, i started with Taupo Car Club 20 years ago, they run a clubmans come winter series meetings off season, these are a whole lot of fun with little expense!! im pretty sure Manfeild does as well? these are generally not advertised but details are obtained by belong to that club!! a great way to start into Motorsport. Also back them i use to attend the likes of "Corvette club" and "Ford Muscle Car Club" track days, i believe these still continue, they great for lots of track time!! but at this "Club Level" its a "all in group" so no "fairness" in vehicle performance! I moved on once the excitment at this level waned.
