I restored mine last year and it was a real pleasure to do. It had been sat in my parents barn for 25 years uncovered so it was in a very sorry state. I stripped everything into components and ended up replacing half of the car (mainly down to me being fussy) but it was virtually as good as new by the time I'd finished. I fitted modern electrics with a 10.5 Orca brushless motor and the whole car's been bullet proof. I've raced it at some big indoor meetings against the modern 4wd buggies and it goes well considering it's nearly 30 years old. A couple of people helped me out on here with parts and the rest came from ebay. It can take time to find the parts you need but that's part of the fun
