It's quite some time since I updated this thread, so here goes.
I've gotten used to the M3 and it is, as Steve Sutcliffe says, "a weapon". Astonishing performance from a paltry 3 litres and a rather podgy kerbweight. On a rolling start, alongside my beloved M4 (F82 model), in the dry and on a smooth road, in relatively warm weather.....I doubt the M3 (G80) would be much quicker, but everywhere else, in every other condition, the M3 is quicker...much quicker. It's simply nuts quick, owing to its traction and ability to hide its rather lardy weight.
Cornering grip is great, turn in is superb, body control is nigh-on absolute and the brakes are actually pretty good. Build quality is almost faultless, with high quality materials everywhere. The ability to surprise 'performance' model Teslas is great fun (they believe a quick 0-60 makes their cars sports cars....not to mention the 0-60 figures quoted are with a 1 foot roll out). It also delivers moderately good mpg, considering its weight and performance and has plenty of room inside and in the boot. Even the looks, something I quite liked by the time I owned one and has grown over time, are praised by more people than any other car I have owned or driven (? Surprised me, given the initial, almost universal hatred of the design). And yet...
I miss my old M4. The M4 was a car that tried to kill you basically. Wet weather was a tippy toe exercise, mid-corner bumps were interesting and you had to think before you flexed your toes. Cross-country and on a rough road it wasn't a fast car, it was a lairy, heart stopping, fun car. I loved it.
It has surprised me, if I'm honest. The general motoring press has gone nuts for the new model, something they didn't always do with the previous version (all except Chris Harris who loved the previous incarnation more than the current one). Don't get me wrong, the M3 is a brilliant car and a wonderful thing to own, I realise I'm very, very lucky, but still.... It's odd really, I recognise the car is better in almost every way and by quite some margin, but to enjoy it properly on public roads, you need to be travelling as escape velocity speeds. The only things I can quantifyably point as dislikes, are the steering wheel (too fat) and the low speed ride (seriously jiggly, even on the softest setting). All the systems work, as does the remote phone app stuff, the interior is a triumph (there are still buttons and knobs) and as a tool to drive quickly in, it's almost peerless in its class.....and yet....
I keep looking at F types Jags, the P450 in particular. A car that is much slower, less well built, doesn't handle as well, has much crappier software and infotainment system stuff. It's thirstier and will cost more to run. It does have enormous character though, that dinosnore V8, the cruder suspension (at least in its handling), some weird design decisions.....and yet....those looks and that sound.
So, go figure. My old M4 (F82) I would rate as a 8/10 car and the M3 a 9.5/10 car and yet I miss the inferior model perhaps it is my age, or the fact that cars are probably becoming too fast to enjoy properly on the public roads (although overtaking is still a hoot). I've always thought that true beauty has to have flaws to reach that elevated status and I think that I'm coming to the same conclusion with cars. A perfect car isn't necessarily the car you want, it's just the car you think you want.
Disclaimer: I do still love my M3, I'm just trying to put into perspective that it is so accomplished, some of the character that can make a car special is lacking imho. In wet weather I do not necessarily agree with that view of course I think only Mustang drivers know the true nervousness of the M3/4 (F80 series models) in damp conditions
