Little suggestion, maybe there could be a number range on the photos when you select the car body for how many passengers it holds, for example 2, 2-4, 2-9 etc. Some challenges require a certain passenger count and I dont know what bodies hold what until you finish building the car only to see it holds less than you need. It could be set opposite the icon for how many doors a body has.
There needs to be more info about the body you select anyway, seat count is definitely one of the important things to know. We’ll add more info as a tooltip eventually.
