1 of 500

In 1974 Lancia built 500 Lancia Stratos HF especially designed for rallys and racing.  They were incredibly successful during the 1970s winning just about all events they entered. They were designed by Bertone and have a 2.4 litre Dino V6 Ferrari engine. 
They rarely come up for sale and if one did it would cost well over £½ million to own one.  This was spotted in that affluent county - Lancashire :-)
