Sport Auto M5C vs GT63S vs RS7





https://f90.bimmerpost.com/forums/sh....php?t=1688615
I am looking at the numbers and questioning choices and values given. While both cars scored the same on KG/PS rating, why is this even a thing? Who cares what KG/PS it offers? The track time vs slalom figures pretty much confirms that the GT 4 Door has a more compliant suspension compared to ars like the M5 Competition, which gives it slightly slower slalom numbers but superior track times due to better grip in varied conditions. The M5C will of course feel a tad crisper on the turn in.
Also, 2 points difference???
Price/value obviously goes to M5C if performance is the key. It's a fine car!








And since I have a tuned F90 M5 which is faster than a CE M5 I am still piqued by the GT63S at the right price of course!!

The GT63s has grown on me though. With spacers and a drop that car looks pretty cool. But then again, the M8 is comfy (happy wife
) and it's faster than the GT63s on the road and on track...

But in the end nobody buys these for track duty. That said, it's quick on the road even with snow tires

The exhaust makes the biggest difference; our E63s still delivers a more visceral driving experience

What follows is highly subjective. In the two months that I've had my GT 53, I've only seen one other one, in rural VA of all places. Its wide stance and squat proportions give it a lot of presence. At this price level, I want a car that looks good on the outside and the inside, and play to my vanity of wanting to be unique. The M5 does not give me this. The interior on the M5 competition also is much less exciting to me than the GT 4Door, or the E class for that matter. MB's interior for now has a much more sculpted and harmonious look, with natural/organic contours that stitch together the different functional elements, each of which fits more or less naturally in their place. The design of the M5's interior is much more disorganized, with jumbled shapes, discontinuous blocks with no sense of coherency. Again, this is highly subjective. It's not about the technology, but the design in terms of placement, shapes, material, texture, and color.
At this price range, and since these are drive on the street, d*ck measuring about track times and absolute lateral grip are a bit beside the point. To be sure, none of these cars are pedestrian in terms of their performance (except for the GT 53, I still have to watch out for the occasional fast Kia, lol). It's much more about the combined sense of enjoyment as you drive the car. If you don't care as much about exclusivity, and find that the M5's exterior/interior perfectly acceptable, then save the money and get that. If you are like me, bite the bullet and pay the premium for the GT 4 Door.

I will have to disagree with some of your points. Performance in a performance car matters and track times are a reflection of the cars capability and composure at the limit. I am less concerned about exclusivity even though we have had the only Edition 1 E63s in the state. Eventually somebody else got a used one but I have never seen it. Similar experience with the AMG GTC. All these cars are rare birds in our state.
On a subjective level, one should get the car they like the most. IMO, the GT 63s just isn't special enough, or fast enough and can't handle well enough to command a $60k premium over the E63s (or the M5). That kind of premium has to be earned somehow. $20k would be a no-brainer. So for the right deal the car can be extremely attractive.








Woflgang, whats a fair discount on the M8? 15%? More?

Which is crazy given that these cars just landed mid/end October on dealer lots and it's a current model year.
BMW just overloaded their dealer network with all these $150k-$180k cars. Not your typical BMW sale...
A GT63s at $130k would be so tempting
