Maserati has made some mouth-watering classics over the course of its history. And it’s not uncommon to see some of them come up for auction here or there. But at its upcoming sale in London come September, RM Sotheby’s will be selling off an entire collection of them – six cars in all, including some rather rare specimens.

Not least of them is a red 5000 GT from 1962, bodied by Allemano and once owned by Joe Walsh of The Eagles. It was originally owned by the owner of the Scuderia Brescia Corse racing team, who drove it to the Italian Grand Prix and subsequently sold it to Italian virtuoso Antonio “Little Tony” Ciacci. It’s been displayed at Pebble Beach and the Salon Privé, and is valued at upwards of £1 million (or about $1.3 million at current exchange rates).

If the classic Ghibli is more your speed, there’s three of them on offer from that same collection – including a pair of Ghibli SS 4.9 coupes (in green and burgundy, each valued at upwards of £200k/$265k), and a white Spyder version of the same. The rare right-hand-drive roadster belonged to the Emir of Qatar, and is estimated to sell for between £850,000 and £1,150,000 (~$1.12-1.5m).

The Ghiblis and 5000 GT are joined by a ’74 Quattroporte that belonged to the Aga Khan (valued at £150-200k or $200-265k), and a red right-hand-drive ’72 Bora (£125-175k or $165-230k).

“This year’s London auction will be all the more diverse thanks to this great range of rare Maserati models,” noted RM Sotheby’s auto expert Augustin Sabatié-Garat. “This private collection of Italian exotica offers collectors the chance to acquire something truly rare from Maserati’s unique history. Some models were once owned by royals, rock stars and racing drivers, adding real character to the group. We are especially excited to see how the Maserati collection performs as collectors continue to embrace classic models from the Italian brand as true investment opportunities.”

The sale is set to take place on September 5 at Battersea in the British capital, but you can check out the whole collection in the images below.
