The 'doesn't feel ready to die' club is an exclusive one, occupied by some exceptional cars. The Discovery 4 probably isn't an honorary member, but it isn't far off.
The mechanical crow's-feet reveal themselves first in the form of stationary refinement - a push of the starter button (especially when cold) sends a small jolt through the cabin, and once settled to idle the six-cylinder diesel sends a continuous buzz through the controls.
Pull away, though, and the buzz turns to a silken smoothness, while at all speeds there's very little wind or roads noise to complain about. The 4's eight-speed gearbox slips up and down between ratios pretty much undetected, too.
The engine also behaves itself well under load. You're tipped back on your armchair slightly as you stamp down on the throttle, while a guttural but distant boom fills the cabin, but the V6 hauls all 2600kg up to motorway speeds with minimum fuss.
In fact, from your elevated position as the driver, and aside from the trees moving past more quickly, the only sense of gathering speed is ride quality. The Landmark's standard 20in rims and relatively stingy sidewalls offer less protection over sharp potholes and expansion joints. With more speed, however, comes less busyness to the ride and more of the Disco's trademark soft but compliant bob over undulating roads.
Bigger wheels don't mean better cornering, but then that's hardly the point. The steering is slow and not particularly precise, but once you've found your line and committed to it, you can rely of the 4's chassis to hang on to surprisingly high speeds through tight bends, albeit with plenty of lateral pitch.
As well as the aforementioned superb visibility for the front passengers, the front two rows also benefit from huge space for four adults. Even a fifth in the middle row's central pew is possible, while another two six-footers will sit in the sixth and seventh seats in genuine comfort even on a long journey.
Access to the front two rows is brilliant, while folding and tumbling the middle row leaves lots of room to clamber up to the rearmost seats. The Discovery's boot in seven-seat mode is a very useable 280 litres to the roofline, while in five-seat mode that rises to a massive 1124 litres.
However, the 4's other Wogan's sideburn is its interior quality and infotainment. The buttons are large and clear, but they're starting to look and feel their age. Furthermore, while the on-screen graphics have brightened and sharpened over the years, the unresponsive, often cluttered menus are lagging behind those of the class’s best.
At least there's a long list of equipment. Climate and cruise control, heated leather seats, a heated steering wheel, sat-nav, Bluetooth, DAB radio, adaptive xenon headlights and a Meridien surround-sound system are among the standard features.
