Those mini-stocks were the epitome of indestructable brilliance weren't they?! I'm not sure if they're still raced these days but I did try my hand at one of Ardent Racing's loaner Mardave V12s a few weekends ago and was immediately hooked again!
I ended up buying one myself and although it's still the classic Mardave racing-on-a-budget style, it's a considerably better car. I even recognise some of the parts in the V12 kit that haven't changed from the old mini stock kit!
Ardent runs a dedicated Mardave/Mini class and in my opinion that's the ideal introduction for the younger drivers. You're much better off learning to handle a car consistently around a track before moving onto a 10.5T brushless monster that bounces its way around the barriers!
No opinion on which is better though - this was my first race in about 20 years too...
