Did I buy my old model back ?? Ex Tamiya 101 star and raced with Rad22Rad

A few years back I built an original vintage XR311 and we used it for filming in the Tamiya101 '19' video. Both myself and Rad22Rad (who used is re-re version) had a great time and they performed really well - better then expected. a couple of years after that I decided to sell quite a lot of my models inc that XR311.. Roll on to around 2018 or 2019 (cant remember now) and I saw a listing for an XR311 - straight away I knew it was my old model. I messaged the guy who lived Manchester way and I agreed a deal and we met have way to save on postage. It was quite funny really cause the guy was saying how he built it and painted the body etc.. As soon as I saw it I knew it was mine.. Sadly the original chassis was no more and he swapped the body onto a new built re-issue chassis. So yes I bought the body back but not the whole car...
I'm not sure what to do with this now, and ive recently bought a partial kit so I may use this body on that with the RCchannel suspension and sell the chassis..
