The biggest cost of owning most of these cars is the value they lose. Worked out from asking prices at UK specialist dealers (for sale now, or sold in the last six months): within each version, each model year’s typical asking price against the year before’s, only where both years have three or more cars. As of 15 November 2026.
Which to choose
The McLaren 750S suits
The 750S suits a buyer who wants turbocharged supercar performance, with 740 bhp and a claimed 206 mph, plus the drama of a mid-engined layout and dihedral doors. The Spider adds open-air driving with little cost to its performance.
The Porsche 911 GT3 suits
The GT3 suits someone who values a high-revving naturally aspirated engine and a car built with track days in mind. It also suits buyers who want to choose a generation: GT3s have been made since 1999, and some years offer a manual gearbox.
If outright pace and supercar presence matter most, the 750S has the stronger figures, with roughly 240 bhp more than the latest GT3. The GT3 gives up that straight-line advantage for a free-revving engine, and in some versions a manual gearbox. It also has a long model history, so there are far more cars and generations to choose from. Pick the McLaren for its speed and occasion, and the Porsche for engine character and choice.

Questions buyers ask
Which is quicker, the McLaren 750S or the Porsche 911 GT3?
On official figures the 750S is quicker: 740 bhp and a claimed 206 mph, against 503 bhp for the current GT3. The McLaren's turbocharged V8 gives it a clear advantage in a straight line.
Which has the more engaging engine?
That comes down to taste. The GT3's naturally aspirated flat-six revs very high and responds instantly, while the 750S's twin-turbo V8 delivers much more mid-range force.
Can I get either with a manual gearbox?
The 750S comes only with a seven-speed dual-clutch gearbox. Several GT3 generations were offered with a manual, though some were PDK-only, so check the specification of any car you look at.
Is there an open-top version of either?
Yes, the McLaren is available as the 750S Spider, which has a folding hard top. The 911 GT3 is a coupe only.
Why are there so many more GT3s than 750S models?
The GT3 has been in production across several 911 generations since 1999, while the 750S only arrived in 2023. That gives GT3 buyers a much wider spread of years and specifications to choose from.
