I would love to comment on the ownership of an m2 competition , but I am in no way experienced enough to, even though I own a 2021 m2c (manual)
I've only driven it 700km over a 4 year period. (I know it defeats the purpose of owning it, enjoyed every km of it)
I did buy speculating that it's value would increase over time, however, when looking at the market and what's being offered for the f87 hasn't reacted to what I expected.
I think that's largely due to the value for money that the g87 brings into the equation.
That being said it brings me joy looking at it in the garage.
