GENEVA.- Bonhams, the leading international auction house, will be returning to Geneva on Sunday 29 September, for a very special sale, featuring a private collection of 25 supercars, hypercars and luxury motor cars – all to be offered without reserve – to be presented at the prestigious Bonmont Golf & Country Club.

The sale will take place in a 12th century abbey, which is next to the Clubhouse, a former chateau overlooking Lake Geneva. It will provide a spectacular backdrop for the sale of such a superb array of high performance and prestige motor cars.

The collection is estimated to realise in excess of €12,000,000, (£10,000,000, $13,000,000).

The cars represent an international roll-call of prestige and performance marques: Aston Martin, Bentley, Bugatti, Ferrari, Koenigsegg, Lamborghini, Maserati, Mercedes-Maybach and Porsche, with models ranging from hypercars to luxury convertibles and limousines.

Highlights include:
