Just get the Miata you want and enjoy it, they are wonderful cars, tons of fun to drive right outta the box. The mods will come, as times goes on, a little here, a little there. Great builds do not happen overnight. It took me 10 years to get my last Miata the way I wanted it, and I swapped out tons of parts on it, some looked great in my head, but once installed they did not flow with the build, so I would sell them off and try something else. I am rather fickle about parts though.
