if you want to have a fast car/buggy, with easy maintenance go for an electric powered one, the new lipo batteries and brushless systems are very good, nitro was never of any interest for me, but they are good when they are running ok, and tend to take a bit more stick.
looking at the pictures, they take me back, started with a tamiya hornet, and never looked back, and the avante, was a proper pain in the a**e to setup.
Bristolbiker, did you ever do the BRCA nationals? spent many years doing off road, racing for Tamiya/Schumacher/Associated, before moving over to Touring Cars, with HPI and finally Xray, good times, but not something i miss now, i can throw myself off a bike better than when i was a kid………..
