I've been bad...
- Thread starter Badbobby
- Start date
I would have preferred red interior and non-black, but I also needed something less obvious at work - so black/black works out.
Don't know if it was a good selection yet! Sounds like the one in Devon is a dog and other options were a touch too expensive as this was the max I was wanting to pay.

Carol M said:Yes, can't argue with that but the pressure distribution over the body surface exerts normal forces which, summed and projected into the freestream direction, represent the drag force due to pressure. The nature of these normal forces combines shock wave effects, vortex system generation effects and wake viscous mechanisms all together.
When the viscosity effect over the pressure distribution is considered separately, the remaining drag force is called pressure (or form) drag. In the absence of viscosity, the pressure forces on the vehicle cancel each other and, hence, the drag is zero. Pressure drag is the dominant component in the case of vehicles with regions of separated flow, in which the pressure recovery is fairly ineffective.
So, to sum up, with the carriage lamp drag is increased by 0.307456 and without you would lose this drag so increasing speed by 5.88678.
Amazing what info you can get of Wikipedia ! :wink:
Verrrry nice!
Two priority jobs, get yourself on the exclusive roadster club, and get the car on the Alpina Register

Don't know what you mean. :evil:
Congrats on the Roadster S .. join the club and get it in on theALPINARegister!
It looks good in that pic, have you got any more detail?

Thanks Wobblewing
Not much more detail available... I've been to get cleaning products, so should be looking nicer at the weekend.
Re the condition, it's not too bad. The person before had a fettish for stick on Alpina roundels (e.g. one over the BMW badge on the front!). Interior is in good nick, with limited leather wear. Front suspension replaced last year. It's had various repaints, but has spent a while in London so these things happen - at the end of the day an 8 yr old car can't be perfect!! I've taken the view that if I keep it for a while, i'll get a full respray and alloy refurb. My aim is never to sell it and keep it as a weekend car if I have kiddies.
So far so good. Met a mate this pm with a 335, so had a bit of a blat....!
