Call me strange for saying this but if I were to vote for a build, I would say the lancia stratos first because it's weird looking. Then the skyline because it's a skyline. Why not tackle a couple?
The Skyline I could build fairly quickly (that might be a month or more for me), but the Stratos would be so much more detailed that I can't imagine finishing in less than 4-6 months. Of course, neither are getting anywhere right now. It's a matter of me putting other things aside and just doing it. I have so many models WIP now that it's overwhelmed me. Of course, every start had the intention of being finished in a reasonable time. Yeah, right. Most of them have at least been painted or ready to start component assembly. My biggest challenge to be honest is that I'm so OCD I get bogged down in detail and quit if I can't get it right. The big Porsche got stuck because the engien was presented incorrectly and I couldn't duplicate the real alternator/fan drive bracket....almost 10 years ago. Stupid, huh? I just can't help it.
I was excited about the Camaro (again). Got out my decals and PE parts and ref pics, then considered the whole painting/polishing issue. Getting cold feet on that one. Last night I found another 100 reference pics for the Porsche. Good Lord! But they do answer questions I had about many of those tiny details I was stuck on. But, you're right about the Stratos. It is different and really cool. And, in 1/12 scale it's a great piece on the shelf or at a show. You're not gonna believe this, but what stopped me on the Stratos is whether the cam covers should be red or black. My ref pics show both, so I actually quit because I didn't want to be "wrong". I know...ridiculous. Maybe I just need encouragement to finish whatever I started.
To make things worse, I started a USS Missouri last year, a 1/32 Atomic Cannon I have wanted to re-build since I was 10, a 1/15 Walker Bulldog, two mre versions of the Revell 1/16 '34 Ford (the one in the pic was a magazine car), and a custom 1/18 Mercedes 300 street rod. Also bought several more that I just couldn't resist. I thought retirement would allow me to do all these long desired projects, but health and grandchildren have created additional roadbumps. My wife doesn't complain, but she thinks I'm overdoing it. I can't disagree.
Oh....and the cars on my Fotki site? Yeah, total restoration of the Mustang, bigtime mods and maintenance on the ZR-1, too much time spent on the others, and all the regular maintenance on the rest of our cars. And, I clean house. OK....maybe that's why I only sleep 4-5 hours a night. It's gotta be some kind of insanity, but I see other modelers with lives who build really, really nice stuff. So, I should be able to at least finish something....right?
I'll go through all the kits again and pick by the weekend. I think. I'll sure try. God help me. This started when I was about 10 years old. Sigh.
