I took a look at the WIP - very nice work. I am a big fan of stock street/road cars when they're well done like yours. They can look like someome was able to shrink a real car down in size.
Heller 1/43 Renault 4CV (that I built awhile back..)
I like your 'real' springs a lot.
Much better then the original pieces - so much so I'm surprised Tamiya did not do it that way to begin with..
