I always wanted a "Hippie" van, so after I retired, I bought a Transit Connect and went wild.
1,148 RGB LEDs, two color organs to drive them, a 400 watt amp built into the upper cargo bin, an extra 550 amp battery on the passenger side, half inch foam on the cargo area floor, and 50 square feet of denim insulation stuffed everywhere I could put it. She rides a lot quieter now.
