The Citroen DS (wikipedia article) is one of those cars. It’s just stunning. Yet it was obviously practical as well, you don’t sell 1.5 million vehicles just because they’re pretty. I could just see myself in one of these, cruising along, looking fast even when standing still. For several years there was a Citroen DS ambulance parked down the side of a house in Fallowfield, gathering patina but still looking beautiful. I don’t know if it’s still there, and I really regret never being able to even enquire about buying it.
There are currently no DSs on eBay, but there is one stunning Traction Avant and a “Big 15” Traction Avant which needs rebuilding. They’re also on my list of cars which would make me glow, and you can get me them for less than the DS.
