Build Your Own Tiny, Adorable LEGO GTI Share Comments LEGO’s creator site has a GTI kit pop up pretty regularly, but the beauty of LEGO is that you don’t need to wait for the company to release a kit. If you have a box full of LEGO and some time, you can make your own GTI. Just like this person on YouTube has done. The MkII GTI uses only a few specialty parts, so as long as you have a windshield, you can make your own GTI. Which is fun. The video shows the GTI moving around, then shows you how to build the car. So this weekend, instead of going out, self-quarantine and build yourself a LEGO GTI.
