Are a massive time consumer. 3/5 vehicles I own are partially custom. Custom paint, custom belt systems, custom cooling systems, custom drivetrain, and todays problem- custom lug nuts/studs. So remember this, custom is cool until you inherit/purchase that custom vehicle with no idea where the parts came from. I always thought custom was neat because “I made that” but in the end, its a big ole pita. End of rant.
