Bit late, but some things I noticed;
On the 3.7 Roadster;
Sump clearance is much improved.
Knee clearance is (much) reduced.
Dashboards is much less nice (put mildly)
Power and torque look fantastic
Time to 100kph has increased?
I think I still want one, the dash can be fixed (MK) but the reduced width of the footwell is a bit of an issue.
On the Aero coupe;
Is the dash made of plastic?
Tax alone in NL will be about 50k euro.
Would have liked the seatback more inclined to get comfy (head was touching the roof) but seats are not adjustable.
Unfortunately that will never bother me because of the NL price tag.
On the +8;
It looks much nicer in the flesh than on pictures.
Dont like the wheels and looking at the clearance around the calipers I think more trad looking wheels might be difficult.
Same issue with the (CO2) tax.
On the M3W;
I had the pleasure to test drive it (not in Geneva). Its a blast!.
It goes well, engine is sweet and rev happy, it handles well, suspension works good. Tranny is a bit noisy but only on decelleration, not a problem. Only difficulty was fastening the seatbelt! Personally I wouldn't buy one but I loved the experience.
