The C-Class AMG C 43 starts at $62,500 while the AMG C 63 S E PERFORMANCE is $86,050. That $23,550 gap buys 5 meaningful differences.
This trim jump changes the engine from 2.0L I4 mild-hybrid Turbo to 2.0L I4 phev Turbo. Everything else is secondary to whether that powertrain difference matters for how you drive.
Start with the AMG C 43 if the 2.0L I4 mild-hybrid Turbo already feels sufficient for the way you drive. Step up to the AMG C 63 S E PERFORMANCE only when the 2.0L I4 phev Turbo powertrain is the reason you are moving higher in the lineup.

That works out to roughly $24,840 more by the time interest is counted. The payment only makes sense if that different powertrain matters to the way you actually drive, tow, or live with the vehicle.
