Maintenance costs GT 43

Hello guys, wanted to know are the maintenance costs of the GT 43 (4MATIC+) similar to that of a C43/E43/CLA45 or the name 43 deceptive? If one observes the purchase price GT is also much more expensive than the other 43/45-er. Is it also more expensive in the maintenance in terms of insurance, inspections/maintenance, wear parts (brakes/tires). I know that the consumption is similar. Especially experience values of owners are desired. Currently I own an E class Coupe 500 MoPf (M odell C207) and in a couple of years I plan to buy me such a car if the price is still a bit lower and in the area where the value loss after resale is no longer as enormous as at present. Please don’t come to me with the standard saying who asks for maintenance costs should not even consider buying an AMG. At the moment I own an E 500 Coupe and my wife A7 3.0 TFSI with 333 hp and it’s no problem financially for us just I want to mi ch of course inform extensively in advance before I buy a car, because as an example if the GT 43 costs as much as a C63 S in maintenance then of course I buy the C63S. Hope for constructive and informative comments?
