A rare single barn find car is reason to celebrate. 230 of them are something else, entirely. Dutch collector Ad Palmen was a car hoarder of the greatest kind and 40 years worth of them in two warehouses and a church. The executors of Palmen’s estate found the cars after Palmen became ill with dementia. The collection includes rarities like a Mercedes 300S Roadster, a Lancia Aurelia Spider, and an Alfa Romeo 2600 SZ coupe. Other marques include Rolls-Royce, Jaguar, BMW, Aston Martin, Ferrari, Maserati, and Cadillac, just to name a few. These well-kept and nicely running unrestored cars should garner serious money when they go up for auction starting Friday, May 19th. It’s unlikely that such a collection will every emerge again.
