An here is it ingame.
As you can see, I have to put the Text a little more down, and maybe use another Location for it, but I think Manehattan is a good Place for a Mechanic Garage. ^^
Ponyvile is to small, Canterlot to highclass... and if you search in the internet for Canterlot, you become mostly the Castle or the Highschool, but it's hard to find a good City Picture.

Fillydelphia would be an Option... but havn't searched for a good Background Picture now.

After I have corrected that Banner, I look forward to make some License Plates for some Special Cars I repaired, restaurated and overhauled were I thought they would match the Mane six. ^^

(It's actualy pretty easy to do them. More problematic would be Logos for painting on different Cars.)

Cya next Time.
