to be honest : bmw are robbing bastar**. I had many over the years, and changed up almost every year. Had the 330cd, m3 e46, m3 csl, m6. The problem is that the service from BMW is so cr**. I went to Porsche and the service i got from Guildford was amazing. They didn't even try selling me a car. Since i've had it, the aftersales is great.
I'm happy to have less technology, since as far as i'm concerned the more technology you have the more goes wrong....i mean you tell me a a BMW m3 or m6 owner who hasn't seen the some error come up on the dash and panic, park up, then re start and its gone again, or the run flat sign blazing up on the sat nav screen and really its just an error that randomly happened.
I went and got myself a c2s, and trust me it is in a world of its own. I mean when you drive it, its just you and the road, no random electronic things messing up. So far i haven't been in for any faults that bother me as yet. Mine is kept garaged and comes out on the weekend, keeps me liking it, and also save me a bit as i don't feel like changing it - and thats after 1yr ownership.
Got a kid on the way, so will be very interested in looking into these child seats for the porsche: personally will prob just use the wifes car!!
Bottom line, just get yourself one.
Also that one you've seen, a bit pricey for my liking....better off getting from Porsche for that kind of money, as you'll get the 2yr warranty with it, and there are a few last time i looked. Mine is a 05 seal grey c2s 30k on the clock, new engine fitted 2k ago, with 14mths OPC waranty left on it, and i'm guessing i'd prob only get 35k at a push, and thats even with my new tyres, new brake discs and pads (fitted yesterady!!).
