I wish I had had enough dosh to buy the set of 1960 Ferrari (Testorosa I think) V12 exhaust manifolds that had been given by Enzo Ferrari and very generously donated and put up for Auction by Murray Walker at the Brooklands BEN auction a few years ago. The reality is that I couldn't never have afforded to outbid the £600 price tag, and even if I could and I would still be wearing them in my lonely bachelor pad, but they were beautifully made, the welds were perfection and the curves so gorgeous, the most feminine bit of any engine / car I reckon.
Sorry to be a bit perverse, but…. One day.
