F90 competition owner here - I drove a friend's G80 competition xdrive and it's just a little bit sharper in the handling, but I can't speak to the base M5. Racing them, stock for stock, my F90 put a couple of carlengths on his G80. They're different enough I think owning both is warranted if you want a choice, but for a do-everything performance car the F90 comp is it. Ideally you would want both for different situations.
I've had my G80 with carbon buckets for about a month now. I don't understand the argument of why dailying a car means you can't enjoy every mile to the fullest. If I wanted to get from A to B in the most boring comfy way possible, I'd drive my wife's Honda Accord. I love the carbon buckets. I'm lean and athletic, and the buckets are only a little effort, maybe a 2 on a scale of 10, but the enjoyment is a 10. I got the G80 because I wanted to enjoy every mile.
Exactly! People consistently tell me I’m lying when I say I love them, enjoy them and have no regrets. People like you and me specifically wanted them and enjoy every moment of it. I wouldn’t want an M3 without them.
It's probably the weight of the M3 that makes it seem faster. I agree with the lag on the M5 as mine has it, and i'm not a fan. I wish BMW would have made a supercharged M5 instead as lag would not be an issue. I think the M3 can be tuned to be faster than the M5.
Honestly bro, I bought mine around 40-42k miles, had it till about 52k miles and I didn’t even bother buying a warranty. The only thing I ever did was an oil change and the previous owners as well. No major issues or changes. I know they have a scary rep but I figured I’ll find out myself and that was my experience
