Building autos is all I have interest in doing.
I love to drive and 'tinker' (some more than just 'tinker' ;-) with my 1:1 cars. I have owned a variety of Honda products (seven different models in the last nine years) in my short life.
Building auto models lets me get familiar with models and makes that I know I won't probably ever own for one reason or another. I also like building cars I have owned or do own. Plus it's easy to get reference that way, I just have to step out into the garage :-)
My favourite build was of a Honda S800. I liked building that car so much, I am now on the hunt to own a real one.
BTW, I have zero interest in Armor, anything that flies or floats! :-)
