Porsche 718 Cayman trim comparison
2024 Porsche 718 Cayman Base vs GTS 4.0
The 718 Cayman Base starts at $68,300 while the GTS 4.0 is $95,200. That $26,900 gap buys 7 meaningful differences.
This trim jump changes the engine from 2.0L flat 4 Turbo to 4.0L flat 6. Everything else is secondary to whether that powertrain difference matters for how you drive.
If you would notice the 4.0L flat 6 every week, the GTS 4.0 makes sense. If not, the Base is the cleaner stop because this jump matters for the powertrain first and the trim badge second.
Think about this as a monthly tradeoff, not just a sticker gap. The GTS 4.0 adds about $473/month on a typical 60-month loan, or around $28,380 more overall with interest. If that different powertrain is not part of your real use case, the cheaper trim keeps more money in your pocket without changing the core experience you need.
