Yes, we have featured a 904 previously but there's enough to talk about with this car to warrant its inclusion again. As an earlier car, in fact the penultimate 904 GTS built, it should have a four-cylinder engine. But through a extensive and varied racing history it now uses a period 911 six-cylinder with the four-cylinder also included in the sale. Its years on track are fascinating so be sure to read the history. It's remarkably original too (alright, other than the engine...) which makes it an exceptional 904. Sounds utterly beautiful as well.
