Shell Valley is a very good company and a very good car. It's quality, just make sure you or someone on your behalf does a wiggle check of everything to make sure the builder didn't take any short cuts. If it's done right it'll be worth it. 4 speed will make your foot box a little more crowded than an automatic but most Cobras are 4 or 5speeds
Good luck and have fun
