What are they like inside?

The Porsche 911’s interior is more comfortable and classy than most executive saloons’ – the driving position is brilliant and there are seriously plush materials everywhere you look.

Climb aboard the Jaguar F-Type and there’s certainly more theatre. Press the start button and heater vents rise dramatically from the dashboard, while a chunky central grab handle seems to fence off the passenger from the driver.

Start prodding some of the plastics, though, and you’ll quickly realise they aren’t as lavish as those in the Porsche. The seats aren’t as comfortable or as supportive, either.

Another triumph of style over substance is the Jaguar’s touch-screen infotainment system, because while it looks flash and modern, it’s annoying to use – mainly because of its complicated menus.

The Porsche’s system is more user-friendly. You can control it using a rotary dial as well as by pressing the screen itself, but either way it’s quicker to respond and more intuitive.

The F-Type is a strict two-seater, and while the Porsche does have a couple of rear seats, these are best reserved for baggage. Folding the 911’s rear seat opens up a flat ledge under the rear screen, which you can use to carry surprisingly long items.

You’ll find the Porsche’s main boot in its nose, though. It’s too narrow and short for a big suitcase, although it’ll take a couple of overnight bags.

Meanwhile, the Jaguar has a shallow single boot in the usual place. There’s even a handy underfloor cubby.
