Sure you can pay more.
Here the auction was for a used 2013 M3W, that was built to someone else's specifications and out of warranty or close to it. In general, the ones built in 2014 and later have various improvements built in and standardized.
Yes, it has a lot of options, but not all are to my liking. It will still have to be shipped to wherever the owner lives.
With the British pound being at an all time low, now is the time to buy a new one not a used one.
I will have a brand new, bespoke M3W (with my selected options) at my house for less than the winning BAT auction bid.
I think the winning bidder paid too much but it's only my opinion.
