Juan, you and I are in same boat. My confidence level has gone WAY down after simple 911 kicked my butt. I have several Tamiya kits I'm thinking about. Looking at Mobil 1 NSX, Canon 956, and WRX Rally of Britain cars. May be easy way out on several of them since they don't need much if any body paint; all are molded in the color they are to be painted. There are some niggling details, and a metric ton of decals to appy to get them to look good. I've also got Revell Texaco Porsche GT1 that I have body in paint but nothing else done.
Back to your question. What do you have in your stash? An easier to decal Supra? That JTCC NSX?
