20 inch wheels and NOT lowered
I also disagree that going to 20" requires lowering. As a side note, I would not use 20s on a coupe (unlike sedan) as it will require tires with too short sidewall increasing possibilities of demage. This will also hurt accelaration (unless its 550).
Just my two cents.

Well, any time you're getting wheels with lips (especially when staggered with larger lips in the rear), these wheels normaly (very seldom there is an exception to this "rule") look an inch less than they realy are. That is because of lips, hence my comment.
And if you do go with 20s, then what your shop recommended is the way to go - larger than "sock" diameter tires (if they fit). I would assume 255/30-20 front & 285/25-20 rear, or 235/35-20 front 265/30-20 rear. Realy not sure if 245/35-20 will fit coupe's front, but if it does it would be ideal. Then you can safely run 275/30-20 rear. And NO lowering needed at all then.

If you're going with 20s with wheel having lips (especially anything over 1/2 inch) then your wheels will look like 19s without lips.
If you're going with 19s with wheel having lips (especially anything over 1/2 inch) then your wheels will look like 18s stock (or even less as stock 5 spoke, not AMG, are all the way to the edge).
Keeping all above in mind (and especially that IMO there is no "right" tire choice for 20s) I went with 19", but no lips - flat face or concave in/out is all fine and is upto you.
For example:
This wheel in 19" looks bigger than most 20s on a coupe (in 20" it looks enormous) - I had this wheel in 20" and have seen it in 19", so I know what I'm talking about:

This wheel in 19" looks smaller than stock 18" 5-spoke (not AMG, AMGs look a bit smaler than stock 5-spokes, IMO) - I have/had both 19" and 20" of similar OZ Giotto, so here I also know what I'm talking about:

Hope it helps.
Remember one thing. If you're going to 19", you will use 245/35-19 & 275/30-19, or even 255/35-19 & 285/30-19(it does fit with "right" offset).
In both cases new tire diameters will be larger then stock - your "gap" will be smaller than what it currently is for sure.
Small story.
Years ago when I was still "experimenting", I used to order several different wheels I liked mounted with different tire sizes I wanted to try at the same time from the Tire Rack. Then I would put each on a car to see the result. Did not drive car with them on - just "test" fit. Then what I did not like I sent back as tires were not driven on and I made sure wheels had no scratches. Obviously I was responsible for shipping both ways (10 or so years ago it was much less than what it is now) plus a small fee of I think $12 or so for them to dismount and clean each wheel. No picture will substitute seeing your specific car with different wheels (mounted with different tire sizes) on it to help you choose. Mostly because of this (and pricing of course), I buy my "shoes" exclusively at TTR for the last 15years or so. I'm sure you can do the same at your local wheel/tire shop if they realy want your business - you will need to pay more for labor for sure, but it still will be less than current shipping rates back and forth.
Good luck.
