Meanwhile, at rival auction house Bonham’s on the same day, a 1995 McLaren F1 – the first of its model to sell in the US – sold for $15.62 (£12.2m).
The F1 was the most sophisticated car the world had ever seen, when it was launched in the early 1990s.
It was also the fastest, with the F1 capable of a accelerating from 0-62mph in 3.2 seconds and hitting a top speed of 243mph. Just 65 road cars were built and this model, known as chassis 044, remains as original as the day it left the Woking factory in 1995.
The Aston Martin and McLaren are owned by different people and had both been valued at around £15 million ($20m), making them the two most valuable cars to ever go under the hammer.
Both cars broke the current record for most expensive British car, which currently stands at $21.7 million for the 1956 Le Mans-winning Jaguar D-Type.
