But his son, Prince Albert II, wants to take the collection in a different direction. We don't know for sure, but perhaps he wants a more focused group of autos. So Prince Albert II is putting 38 of the cars up for auction.
A few of the more interesting lots are the aforementioned 1939 Simca 5 expected to go for between 8,000 and 10,000€ (about $12,500) and a rare 1973 Camaro export model with 43k kilometers on the odo. It's described as being in very good shape, but its inline six keeps the expected sale price to between 8,000 and 12,000€ ($15,000).
On the high end is a 1924 Panhard & Levassor X47 limo with a Weymann body. Weymann, the auction catalog reads, was known for making lightweight, aviation-inspired bodies by stretching imitation leather across wooden frames. This car's rarity and superb condition could push the top bid to and estimated 35,000€ ($44,000).
The auction takes place on July 26 in Monaco. All the cars to be sold can be seen on the auction house's website or you can download a PDF of the catalog here.
