X 1/9 Infos

Hello together! I’m playing with the idea of buying my girlfriend her X 1/9. (Was her first car and it’s been in the garage for 5 years – but was restored before decommissioning at that time.) I estimate the condition to be 3 (but maybe I’m also too pingy). Transmission and new doors he needs – otherwise everything looks pretty good. Except for the usual little things. And ‘n 2. there’s a battle drive. Is Bj. 80 or 81. My question, where can I find information about the car? Here are some models, motorization, possibly fags list for old vehicles etc.? At google you are looking for yourself almost dead and I just need some standard information. What do I have to pay attention to? What’s good, what’s not? Am I quite assuming that I can drive an H-mark, starting from a vehicle age of 25? (or was it 30 years?) What does a car swallow? What about spare parts? Thanks already in advance for your “help”
