Would now be a good time to bring up the way BMW briefed the motoring press on how the suspension of the C differs from the LCI (and OG)? It doesn't, but the supporting structure does and appears to have a significant effect. Which the press may have noticed, or possibly just reported.

So: It looks good, it may have an effect on the way the car feels to drive (mostly due to a change in stiffness, rather than weight reduction - fitting a sunroof will have a bigger effect), it might be possible to retrofit (as it appears in the retrofit section of RealOEM.com).

Don't think so. That's the MPerformance carbon roof in there, which has been an available aftermarket part for a while. That's not a new thing. Nothing in there is calling out CS construction components. There's video reviews and everything from BMW Blog already showing the component and the completely different attachment points etc.

If you live in Australia and love your car you don't park outside of cover aside from brief periods. So It's a moot point.
Many people live in places without covered parking.

No matter how much they "love" their cars. That isn't going to change.

That carbon fibre plastic crap just isn't designed to withstand the elements without protection.

"That carbon fibre plastic crap" what a laughable comment

Life choices and priorities. All depends how much you love your car really, which will then factor into where you choose to live. Paint, interior, rubber, everything is going to turn to shit if you park it in the sun everyday for years.

Great job highlighting this imperfection..

IMHO, it's really small potatos and barely visible, unless it's specifically accentuate.

I wouldn't even entertaining the thought of having some dealership oil jockey put his dirty paws on my vehicle, in attempt to replace the roof, since extrapolating from how this incident came about, leaves a distinct possibility that the replacement part would entail the same cosmetic blemish as the original.

I know this might sound like sacrilege and ironic to some but if it really irked that much, I would probably just paint the carbon roof in a glossy black hue to disguise the said flaw and call it a day, before resorting to having my low production vehicle hacked up.

I hope CS owners find closure in whatever avenue they choose to come to terms with this issue and it doesn't discourage them from an otherwise remarkable piece of machinery.

Looks great. Like a motion pattern when the finish flag is being waved aggressively. I consider it a feature. But then again, I was originally born in England so I have a genetic predisposition to embrace quirks as features.

this type of work is typically outsourced to the local body shop. oil jockeys tend to not actually do the work they aren't trained to do.

A roof R&R, give or take a few steps:





Ain't no way anyone is doing this to my hypothetical brand new CS, in attempt to repair it.

I'll paint the top black and be contented knowing that I could have a have $8,000 CS carbon fiber roof and still conceal it because I got it like that..

I'm not 100% but I'm pretty sure a roof swap would be an in-house job. I've noticed there is an entire passage dedicated to this, in the dealer training manual.

So let say this is true, in theory, one would assume they would summons their highly knowledgeable "Master Technician" for an intricate job like this but from want I've learn, in practice, anyone clocked in for work, that has a minimum of a ASE certification and read a shop manual, gets the ticket that day. It's a roll of dice, the foreman uses the manpower he has..

It a car basically a machine with thousands of parts working in unison, it's not rocket science. My issue is room for human error and possible blowbacks from having to tear-ass open my lid. As a wise man once said; "Shit Happens" 🙌

It seems the production process has improved since time has gone on - at the end of the day, even for someone particular like me - this is a minor issue that could be perceived as a feature and makes the car even more unique if this ends up the only car with the pattern.

I feel most CS buyers are secure enough in their purchase to not have this be a major detractor from their enjoyment.

My opinion about the roof , is that it will become a feature to have unique imperfections on the roof .in reality this is so minor that i havent even look at those imperfections since August ! Anyway , Imagine reviewers after 15 years , joking in a good way for those imperfections , having 2 CS aside , and looking one another and joking where each car has its imperfections . So not only the car will hopefully get some good comments after years , but if this topic with the roof becomes more well known , we will end up joking on wheres the imperfections on any car . And how cool that will be !

I was joking and serious when I mentioned you would always be able to track your car by the roof pattern. It a unique identifier.

Well? You're supposedly oozing with real world experience on the 'business' and you have nothing to add countering my claim but humble bragging?

So tell me, how are you certain whom is assigned what specific job at a franchise dealership service department?

Bahah omg that is so true, I love it.

It's another way to tell the vehicles apart, "my CS has 4 wavey squares on the passenger side and yours has it near the front "

Well, I was only replying to your reply to my post so in order to avoid turning it into an argument I purposely refrained from expanding on the thought, which I will continue to do. If you want to decide you have it figured out, that's fine with me. I have nothing to prove to you, it doesn't pay well enough.
