Tearing another car apart while another or two are still apart. I swore I wouldn't take the GTS apart until the Barracuda was done...Barracuda still isn't done (started in late 2007) and tore the GTS apart in 2018. It's not so much having multiple cars to do, but it's about having limited space to store them. Then you add the parts I have here for my son's Dart and you have a mess...
