My friend has had three Quattroportes - having come from Astons which were getting 'too much like a Mondeo!!' according to him. His Masers have been reliable but eye-wateringly expensive (mostly depreciation). However, he can afford it and absolutely loves how the car feels and sounds. That is surely the whole point and what you make reference to in your post. They're not for me, but I can certainly understand why someone would want one.
Depreciation is why I bought my SL500 for £10k instead of £90k new. I figure I can have some fun for a year or 2 and then trade it in for close to what I paid. If I get any potentially horrendous bills I can trade it in early and only lose a few grand.
