On reflection I think I should take the "mid-life crisis" comments as a compliment. Next to the Z4 on the driveway is my gleaming Focus ST estate. That is faster, noisier, and was more expensive than the Z4, but because it looks like any other mainstream estate car, it gets ignored. The Z4 is "different" so attracts attention in one form of another. All publicity is good publicity.
I also have a bigger house and garden than him, am 15 years younger than him and have retired earlier than him. If I were to be cynical, this may have something to do with it.

drive what you like, and if you don't like it then do something about it!
