I don't know about the display per se for the 918 Spyder as it seems to just be a song playing display which is fine. But it does seem the metals on the interior are different than the metal choice in customization, so that could be fixed. As well as some of the shading in places
There are a lot of body kits that do not have the trim color/type applied to the parts it changes (For example, look for one that changes the exhaust like on the BMW M5 E34). It looks really odd but I imagine this must take a lot of time as the model itself might need to be modified.
@Creepis Yes it's very time consuming, which is why I'm asking about the worst offenders first. But things like the standard Veyron have parts that should be metal but aren't, is something that really bugs me. I'm trying to figure out what ones need doing badly and I can do a quick pass to fix metal issues first then I'll get around to the more detailed shading fixes another time.
@Bnjemann I don't think it's the gearstick that's the problem, I think the driver is just really worried that old truck will breakdown at any given moment.
