My question is already stated in the topic. I always build skill level 2, but this value pack of cars I bought has two skill level 1 autos. I already have some ideas: maybe cutting the seats off, painting them, doing general detail painting, etc. However, I don't think there's any way to make an engine for it; I guess I could, but it would be much more intelligent to not waste all the effort and just buy a skill level 1. Anyway, tips would be appreciated.
