Went to see it today - did not test drive it, but had a sit and play with the roof etc.
The one is was in was the top spec model and with all the toys, including upgraded wheels etc it was £44k.
It is definetly much better in the flesh, love the front end, not sure about the back. I love the looks of the Z4 Coupe, but i am a roadster fan, so this is the best of both worlds. It is definetly better than the SLK, i had an old Slk and that was fun, but the new ones just too soft. Loved the inside and all the toys, but i would need to spend money to get what i have in my current M.
It feels much larger, more like a tt inside, the new sat nav screen is great, but they quoted me £1900 for that.

Great boot space until the roof goes down and has a stupid contraption that has to be in place prior to the roof going down, just like the SLK.
There was a string of people wanting to look at it and they had already taken several orders. Very limited discounts offered and only if you where buying all the bells and whistles.
The colour choice is naff, even the special colours are limited. Why can Audi offers 30 odd colours including 5 purple shades and BMW cannot offer anything particulary special.
Will i buy one, not at the minute, for £40k odd think i could spend it more wisely and do not think it will be as fun as my current car. In a few years might consider one when i can pick one up a few years old.
