W209 bodykit on w203

[Mannmade]

I'm torn between a w209 and w203 I love this kit for the w209 but would probably prefer the w203 for the room. How far off would I be if I tried fitting this to the w203?

To my untrained eye the cars look almost identical other than ones a coupe the other is a more door

The rear arch leading edge may be ‘overlapping’ the rear door; not insurmountable, but will add cost due to complexity of adapting, and ensuring that it is fitted strong and stable, ( so any part mounted to door can withstand a few years of slamming without the paint cracking at any joints.
Sill maybe slightly longer on a 4 door, so again costs of adapting...(looks like 125mm longer)

Nice kit though

Yeah I knew the skirts and arch would need modified. It was more the bumpers and front wings I was concerned about whether they were direct fit or completely different

A2038800318
A2098800318

These are the numbers for the wing does that mean they're different entirely and won't fit?

I know with nissan the silva s13 and 200sx s13 are interchangeable
