Looking good, one thing i can say is that tamiya makes decent decals. So you shouldn't have to worry, and if they get yellow use the method that was mentioned. Also there are other decal replacments.

Nice collections, since your worried about the decals then i would start with the older kits first. Like volvos first, supra, opel and last the mercedes and alfas. It also depends on the decal condition. Good luck.
