Mercedes-Benz AMG GT trim comparison
2024 Mercedes-Benz AMG GT 55 vs 63
The AMG GT 55 starts at $134,900 while the 63 is $153,350. That $18,450 gap buys 5 meaningful differences.
Same engine, same drivetrain, same fuel economy. The $18,450 gap is pure equipment.
The 55 is the cleaner stopping point if keeping roughly $324/month in your budget matters. The 63 earns the extra money only if you want the nicer equipment factory-installed and under warranty.
If you are budgeting this move monthly, the jump from the 55 to the 63 is about $324/month on a 60-month loan at 6.5% APR with 10% down. That works out to roughly $19,440 more by the time interest is counted. At this end of the market, the payment change usually matters less than whether the added equipment actually changes daily use.
