Porsche 917 SofaThis Porsche 917-inspired sofa is the perfect accessory for any auto geek, featuring a "front end made of fiberglass just like the original race car -- slathered with nine coats of paint in the same style of many of those speed demons of the era." Product page here.
Sure this model is lacking around 1,100 horsepower or so (from CanAm setup), but the company that makes it will paint it in your choice of livery. We'd of course stick with the Gulf-Wyer trimming. Just £3995.00 (~$7500) takes one home[Source 1 - 2]
