Hi not sure if you are the person to contact about Columbo's Car. I would like to find out the owner of the car it and see if they are taking offers. Maybe they can auction off the car or raffle it off.
Sorry I can't really help. There have been several Peugeots used over the decades, and one of them I believe Universal still owns and uses -- it sometimes shows up at Universal in Florida, or in various touring displays. I doubt it's for sale.
We heard from a guy named Paul Leverenz in San Diego who worked on one of them for a friend (name not given) in the San Diego area, but that in itself isn't much of a clue where to find it now. The story is in the Scrapbook area of this site:
Hello everyone long time lurker on this great forum, I work in the film business and for years I saw the 403 on the Universal studios back lot by gate 4, I always wondered why it was just parked in the same spot for so long and if they even knew what a classic it is!
