So there's this pretty awesome game you can get if you have a gaming pc. It's called SLRR (Street legal racing redline). Some of you might remember it from the early 00's as it was made by Activision. It's basically a game where you can build up your own car, in depth, and by in depth I mean really in depth. Nowadays there's plenty of modders out there who have made the game better by adding real cars and real parts to it. Which means you can build up your own MX5!
You start essentially with a bare chassis as pictured below and you add everything: running gear, body panels, engine (you can actually build your own engine too starting from the block, choose pistons, valves etc.), aero, wheels, brakes, shocks, springs, literally everything.
Here's some more info on the game: https://en.wikipedia...Racing:_Redline
Wheels, engines, cars etc. you download from modding websites dedicated to the game. You can have about 200-300 different wheels for example.
So there are proably some of your cars that you can replicate on the game, obviously it will NEVER be as accurate as the real life version. For example nobody has modeled a Deuce kit yet, or nobody has modeled a TR Lane cage or Cusco cage.
If you want the game I can message you some links
