SL43
Arrow HELP wheel upgrade question

Hi MBWorld! I know next to nothing about cars except that I love my SL. It's my second SL and yes it's had a bunch of electrical probs but most seem to be solved. Anyways, I have the poor mans version the SL43 and I wanted to upgrade my 19 inch wheels to the 20 inch wheels (stock from MB that were on the 2023 SL55). When I purchased the car (not at my local MB dealer, this one is 1 hour away), I negotiated a lower price for the wheels but now the dealership is telling me they can order them but won't install them because they didn't come stock on the car. Does that sound right? I have to believe MB dealers have upgraded wheels in the past. But let's just say they can't/won't and I at least order the wheels from them and have them installed somewhere else. Am I walking into problems?? Such as: (a) they won't fit (hard to believe since I've seen SL43's with a track package and 21 inch rims on them) OR (b) the brake rotors/calipers won't be big enough? Are there any real considerations or am I overthinking it? Just get the wheels at the discounted price and have someone install them and maybe take it to my local MB dealer for Tire Pressure calibration? Really appreciate the help!!!!
