Ok...not an M3W owner but......the modern version is that...a new take on the originals.
Mudguards do not seem out of place in that circumstance. It is after all not an daft replica. They can be customised to whatever you want....ultra modern or retro.
A Gulf liveried M3W has the looks to fit in with the GT40 era cars so some added tweets to enhance that is fine with me.
The WWII livery......also up for refinement.
