Do you want it for 'the Vintage-factor' or 'the FWD experience?'
If it's the first, I can honestly say from restoring one that the Maxxum is a very nice piece of vintage machinery: Besides the different concept it's got some nice and different features in the design
There are a nice few upgrades for the car which will give you a nice hunt for upgrades, although if I recall correctly, the car was good enough and sturdy in the basics... Just not very practical at keeping dirt away from the electronics with the bodyshell serving as a scoop
Also, the concept doesn't offer the best performance that FWD has to offer.
So - without trying to make it too much of a sales pitch - if you're looking for the highest performance, you might want to consider checking out the '
ORB Racing FF210' buggy...
PS: FWD buggies are 2WD-legal under BRCA and EFRA regulations - vintage racing is a bit of a different story, and depends very much on both your model and where you're racing...
