What have you done to your car to make it more enjoyable?

Suspension/tires/brakes were a big one for me. Just made if feel more modern to drive.

Recently though, I dropped the dash harness to chase an electrical gremlin (which I'm not sure I found) and while I had it out I rewired the harness to remove the seat belt interlock, wired in a chime from a ZJ Grand Cherokee and changed out the headlight switch. Now the chime (instead of the old buzzer) runs when the key is in the ignition or the headlights are on and the driver's door is open, but only when the ignition is off. Used to bug the heck out of me that it would buzz when the car was running and I had the door open. Changed the headlight switch so it completed a circuit for the chime when it was on. Only reason to dump the seatbelt interlock was so I could use some of the wires for the chime and to make sure it didn't cause a no-start issue someday down the road.

Now I need to figure out how to build a headlight pull that doesn't look like a huge wart on the IP. The new switch is deeper than the old one and while the old pull worked you had to use your fingernails to get behind it and pull it. But the honkin' huge one works for now.
