Simply one of the most accurate, detailed, and well-handling antique car mods I can think of. It's a great way to experience the very earliest GP racing, especially on dirt roads and early ovals. Love the added Lua functions (the radiator!), physics/damage model, intricate shifting, and just how much you can slide this around corners. (Make sure to adjust your engine braking points for it, and go light on the handbrake when needed.) I'm already looking forward to the next pre-WWI racers and sports cars of note!
