1955 BMW 507

The 507 was packed with a 3.2-liter V8 engine that produced 150 horsepower, reached a top speed of 122 mph, and could accelerate from 0 to 60 mph in 11.1 seconds. Although BMW pulled the model in 1960, it now collects above $1 million from buyers, with one 507 going for over $5 million — the most expensive BMW in history.

1956 BMW 503 Cabriolet

The 503 was a luxury two-door Grand Tourer with a vertical two-piece grille, two horizontal grilles, round headlights inside rounded fenders, a thin chrome front bumper, and a hood with a slight slope. It packed a 3.2-liter V8 engine that produced 140 horsepower, and it could reach 60 mph in 12.8 seconds with a top speed of 118 mph — but BMW stopped its production in 1959.

1962 BMW 3200 CS

With 603 units produced from 1962 to 1965, the 3200 CS, a two-door coupe with two taillights, was the first-ever BMW to feature the Hofmeister Kink — an element consisting of a forward-angle made at the base of the C-pillar of cars. It was powered by a 3.2-liter V8 engine with a four-speed manual transmission, and it could do 0 to 60 mph in 8.9 seconds with a top speed of 124 mph.

1973 BMW 3.0 CSL

3.0 CSL, the track version of the CS series, sported a 3,153-cc engine producing 206 horsepower with a top speed of 137 mph. BMW efficiently used aluminum to make the doors, bonnet, and boot lid of the car, and its power to weight ratio was 6.1 kg/hp — not to mention the specially-shaped rear spoiler which gave it the nickname “Batmobile.”

1978 BMW M1

The M1, all 460 copies of which were hand-built from 1978 to 1981, had a 3.5-liter, straight-six motor, producing 277 ponies and 243 lb-ft of torque output at 5,000 rpm — with a Kugelfishcer-Bosch mechanical fuel injection system helping it reach a top speed of 162 mph. Later, a sports car version (M1 Procar) was created for world championships and the M1 Procar Racing Series.
