I finally settled on
4 door
SSII
Fox Red
Carbon Fibre Leather
19"
EDC
BT
USB
And a few other odds and ends, ends up at £54k
I really hope your right about that depreciation, I'm surprised people would pay more for a 3 year old M5 compared to M6, maybe a 4 door M3 will go for loads
If you get over to NE Scotland in the summer I'll take you for a spin
PS apologies to the OP for going off topic a bit
