If you are rich, and a fan or certain cars for their beauty and looks, then I see no problem with it. I don't think I'd buy ten of them tho. If I never intend to drive the car in question, then I'd buy just one and have it in a "showroom" museum to look at. Not much point in having ten, unless you intend to keep the other 9 and sell them on later for profit, should valuation go up on them.

If I was loaded and money no option there are a load of cars I'd happily own purely to look at and not drive - just have them shiney and polished sitting in a showroom at my extensive country estate so I can look at them
