Nathanael, I was able to complete this design tonight. I spent all day thinking about possible ways to connect the engine top plate and hood top plate in ways that will make them fit correctly while still being very sturdy. I learned several new techniques that I can use for my own designs. Perhaps my solutions are not exactly the ones that you used, but I made a big conceptual leap when I realized that these interior structural areas need not be symmetrical and in fact it may be impossible to make them symmetrical in order to make a finished model that is. I also used some parts in ways that I had not considered previously. Again, thanks for these excellent designs that are really helping me to improve my building skills.

Incredible! How you make all these MOCs with if few parts and as many details. Really excellent...

You and your alternate set MOCs. Beautiful work! I always envy poeple who can pull somthing this stunning out of very limited set of pieces.

Thanks for your kind words! I'm glad to read that you also find your way back to LEGO, and about your experience that you really enjoy solving the challenges that are present in my models. It's one of the reasons why I build and present things the way I do. If you really get stuck, you can always send me an email, and I will help you further on your way.

As an adult who has just recently gotten back into Lego, I had a great time today building your Unimog which was the first thing I have built using some SNOT techniques. I was very proud of myself when I completed it and then set out to build this race car. At this point, it is 90% or more complete, but I am struggling to figure out just how I attach the two top pieces at the front and back in a way to make the curved pieces firmly attached. I guess I just need to study some of these SNOT techniques to figure out where I am going wrong but I must say that trying to build this has been a wonderful exercise and I am looking forward to figuring out whatever techniques I am unsure of necessary to complete this.

Another really nice, well proportioned model from this great set. Coming up with thus kind of variety is not as easy as you make it seem. You sure have gotten your money's worth on this set!

Very nice. I love these old school race cars. No fancy technical stuff just pure racing. Seven alternates from one set - very impressive. Thanks for commenting on my stuff.

Sweet!

Nice job. You already have build a tractor-truck, a jeep, a quadbike, a F1 car...maybe you could try to build one of those spyder by Bombardier, you know, these three wheels motorcycle. They look good and it could be challenging with a car-based creator set.

Wow, this is one nice MOC! Simple design, but looks really great.

Very nicely built.

nice SNOT very nice shape. great job!

Congrats: simple yet sophisticated; my favourite out of this series. May I suggest something like the Wazuma V12? http://www.motorevue.com/site/video-essai-du-delirant-wazuma-bio-v12-43164.html
