Some sets feel bigger than the box they came in. For me, that’s the LEGO 948 Technic Go-Kart — one of my first LEGO® sets ever. I still don’t know how my parents managed to find it where we lived back then, but they did, and this little blue kart is the reason I fell in love with moving parts and mechanical builds.
