I had me one..an immaculate 1971 Caddy ambulance (that one in your pic appears to be around a 1960 model) . Converted it to the ultimate party-mobile, which was very easy since it came equipped so well right out of the box.
472 CI engine...massive Leece-Neville low-RPM alternator..AC inverter..plasma cooler...climate control front and rear...
All we did was add cushions/bed/table in the back and a kick-butt state-of-the-art 8-track stereo and we were in business!
Could park it anywhwere. Anywhere at all.
*sigh* sure do miss that ride.
