Yes, however one offs almost never have data outside of price and in limited circumstances mfr est 0-100 and top speeds. I would not consider either to be warranting adding functionally a separate wing of the website

And one-offs are gateway drug to things like "I made this in my shed" home made things etc.

we'd benefit more from allowing every racecar in that regard

@FastestLaps were do i sign?

Actually I think garage customs can be useful. The scca stuff im doing is mostly garage stuff after all and its literally hundreds of laptimes

Absolutely. Been saying this for ages

on another note, how would the naming convention work? would the team (if non-OEM) be included, or it's just model name + class?

Thats how I've been doing it. I put "name" "class" "distinguishing feature". Like these
