This is my first Add-on car, works fine. Only, I could not find a way to make my tuning parts available. After lot of time waste spending in attempts, I finally decided to set mod kit to "0_default_modkit". That way car at least has some modifications.
Anyway I included all tuning parts in the .dlc file, so if you are an expert you may want to try to make it working. Please let me know if you make it, i would like to learn it too. Other things are good.
I edited carvariations for 2011 Mazda2 colors, but you can allways edit it if you want (and if you know how). Driver position is good, hands on wheel, handling good, I guess... other things... breakable glass, lights, damige, inner glass (doesn't turn dark after upgrade), 
lights ok, dials in mph ok ... anyhow... check it out :)

Installation:

Firs choose folder with your prefeable plates shape, and follow the instructions inside it.
