Back in 1975, US artist Alexander Calder did something unspeakable to a pristine BMW 3.0 CSL.
He covered it in paint. Lots of paint. Red, white, yellow and blue, arching over the car's angular bonnet and wheel arches, the body acting as a canvas for Calder's typical style of primary colours and bold shapes. So captivating were the final results of Calder's project that it spawned a unique chapter in BMW's history - it was the first of the Art Cars.
16 artists have followed in Calder's brush strokes since then, adding their own unique artistic style to iconic BMW's over the years.
To mark the 40th anniversary of the founding of the motoring collection, BMW has recalled each of its 17 Art Cars for a rolling international exhibition, starting in Hong Kong, before heading to New York, Miami and Shanghai.
Now this is the kind of modern art we can get behind.
