Slightly improved suspension on most model equivalents, CID Nav (good for the time), less cluttered headunit controls due to double din facias, non-toffee wheels on the MV6, no rusting door tops creeping down from the weather seal, door rubbing strips that don't bend back on themselves.....
Suspension improvements I've struggled to notice TBH.
The NCDC/CID setup is a big enough improvement to make it worth retro fitting back to MFL, which is fairly trivial
Not sure I agree with improved facia. Maybe its familiarisation, but I've always preferred the earlier layout. Plus you can replace the switches with PFL ones as they have the same hopeless covering as FL.
Rusty doors is the big problem with PFL/MFL
As for MV6 wheels, well, yes, agreed, Irmscher need shooting. TBH all Irmscher wheels are made of chocolate, but the MFL MV6 ones are a disgrace
