Hex code first experience (ignore the nice category)

sometimes when i'm playing multiplayer some players got impressed with my hex coded car, they never seen this before and i feel cool for some reason. but i can understand them because imgaine you're playing and suddenly a guy pops up with a Mazda 787B even without mod, some impossible car silhouette or a fuhing kart with a side exhaust. my first hex experience was at own frlmods site when j was exploring modpacks, but if i saw this at multiplayer i'd probably be impressed too. how was your first hex code experience?
