Well I'm a hairdresser for a living so it was the obvious choice. (GROAN).
As a young man my ambitions of car ownership we're generally trying to get bang for buck in terms of looks and speed. Having had several cars I had a 57 Audi S3 for about 2 years suddenly realised houses are quite expensive... sold the car (my only real chunk of money) and bought a £750 Mondeo which did for the next 3 years....
Still saving for that house but the petrolhead in me could justify a couple of grand on something a bit more exciting car wise.
I fancied doing the North Coast 500 and having had 'a go' of a mates MX5 thought the 500 best be done in a drop top sports car.
Looked at the usual suspects S2000's etc but too much cash. Wasn't impressed with early boxsters build quality (not a patch on the Z4 - feels cheap inside in comparison)
I was suprised to see how good value a Z4 is. I bought my first 03 3.0i for 3k with 111,000 miles on the clock. I overhauled the suspension and got it in top condition, had for about year and crashed it

A low speed affair believe it or not.
I felt so guilty seeing it go on the low loader! Took the insurance cash and the car is back on the road somewhere according the the tinternet.
I started my car search again and I just could not find any better car for the money than another Z4.
This time a 2006 3.0si. Silver (the whiter silver?), nice aftermarket multispoke M wheels, red sports seats, fat m steering wheel and aftermarket suspension all round.
Both my cars turned heads, which I think can't really be said for most cars costing in the low thousands - I don't buy cars to show off but hey its nice to be noticed!
I love getting the roof down on a sunny day. Any excuse. It just adds to the journey. I also think it makes you want to seek out a journey further a field on a nice day. I love the noise of the straight 6. I love the bang for buck. I like the smallness of the car. It feels like a hark back to sports cars of old.
It's fairly practical too, manages my costco shop no bother!
I would like an M lite next but I also really don't want to lose my drop top ability! (And an m235i convertible seems even more hairdressery to me..)
