BMW M1

The BMW M1 (E26) was a sports car produced by BMW from 1978 to 1981. In the late 1970s, Lamborghini entered into an agreement with BMW to build a production racing car for homologation, but conflicts arose that prompted BMW to produce the car themselves. The car employs a twin-cam M88/1 3.5 L six-cylinder engine with Kugelfischer mechanical fuel injection producing 273 hp, giving a top speed of 260 km/h (162 mph).

Turbocharged racing versions made around 850 hp. Only 453 production M1s were built. Of these, 20 were race versions created for the BMW M1 Procar Championship. The BMW M1 was possibly the first everyday supercar.

The M1’s 24-valve, 3.5 liter I6, dry sump, mid-mounted engine was a gem. 0-60 came in 5.4 seconds and 8 seconds to 100 mph. That’s quick by today’s standards but was huge in 1980.

In 2015 an incredibly rare and immaculate example of the BMW M1 made £603,000. That's roughly double what an ordinary M1 goes for. The M1 remains a highly collectible car.

Factory restoration of a Porsche 911 2.5 S/T

This 911 2.5 S/T was discovered deteriorating on a playground in the US.

The car, which raced at Le Mans, was in a critical condition: rusty, bent out of shape, wonky – and very far from road worthy. On the straightening bench, the body is checked and restored to its original shape. Special metal plates are affixed to each of the axis points on the body, and are pulled using a hydraulic dozer and a steel chain until the body is back in shape.

Experts reconstruct the body step by step. This painstaking process is done by hand and takes over 1000 hours. With the help of original Porsche body jigs, restorers work precisely and keep to the correct dimensions.

For the 911 2.5 S/T, many body parts needed to be custom fabricated based on original Porsche drawings.

After a Cathodic dip painting for corrosion protection, the body – including the underbody, engine compartment, the trunk and the interior – are painted with primer. This is then followed by factory painting by hand. After a curing period of about eight weeks, final assembly can begin.

The car is an extreme rarity: only 24 of this racing car, based on the 911 2.4 S Coupé, were built. The 911 2.5 S was a works-modified version of the standard 911 2.4 S Coupé designed for use on racing circuits and modified in accordance with international sporting regulations. Racing, in particular the Le Mans 24 Hours race, is of great significance to Porsche. Over 800 Porsche vehicles have taken part since the first race took place in 1951, with 103 of them taking a class victory and 17 overall victories making Porsche the most successful brand by far.

1953 Fiat 8V Supersonic by Ghia

The 8V is Fiat’s most legendary, significant, and storied production model. The most striking were the 15 bodied to Giovanni Savonuzzi’s stunning Jet Age design, known as the Supersonic.

The Fiat 8V had a 70 degree V configuration displacing 1,996 cc and fitted with two twin-choke Weber 36 DCF 3 carburetors. In its first iteration (type 104.000) the engine produced 104 hp at 5,600 rpm. The improved type 104.003 made 125hp. The engine was connected to a four speed gearbox. The car had independent suspension all round and drum brakes on all four wheels.

Only 114 of the high-performance coupés were produced. Regardless, they continued to win the Italian 2-litre GT championship every year until 1959. Eight 'Supersonic' are thought to have survived.

A 1953 Fiat 8V Supersonic by Ghia sold at Amelia Island in 2017 for $1.3m. This example is another gem from the Elkhart collection. It made $2m in 2022.

Cavallino Rampante - Prancing Horse

On 17 June 1923, Enzo Ferrari won a race at the Savio track in Ravenna where he met the Countess Paolina, mother of Count Francesco Baracca, an ace of the Italian air force, who painted a horse on the side of his plane. Baracca was Italy's top ace of World War I, with 34 aerial victories. The Countess suggested Ferrari should use the horse on his cars, saying that it would bring him luck.

Baracca's luck ran out on June 19, 1918 when he was hit by ground fire on a strafing mission. Baracca's burnt remains were recovered from where they lay, four meters from the wreck of his Spad VII aircraft.

Ferrari has used the cavallino rampante on official company stationery since 1929. Since the 1920s, Italian race cars of Alfa Romeo, Maserati and later Ferrari and Abarth were (and often still are) painted in "race red" (Rosso Corsa). This was the customary national racing color of Italy. Stud farm in Italian is scuderia.
