My pickup is on a 25k service interval. Had it's first service recently and all they did was an engine oil change. Didn't even take a wheel off they rely on the computer to tell them when things need looking at. It's to make them cheaper on lease deals etc but I'm not at all impressed. That means it'll get to 50k with no-one looking at anything. I keep cars a long time so it'll be having an annual service at a propper garage rather than a dealer from now on.
Every truck and trailer for the last couple of decades has run on air bags and the only problems I've ever encountered are valves leaking. A vosa fail but not journey stopping. Not that I have a fleet of hundreds of trucks mind 🤣. I can see why you wouldn't want it if your in the middle of nowhere hours from anyone with no phone signal but in the UK where your filmed and posted online as a yob if you drive on the grass verge I would quite like it. Partly as I've had 3 coil springs fail on my van in the last year, one sticking into the top of the tyre 😡 although I guess 200,000 miles isn't too bad.
People want them to make an ultimate offroader, that's like homer Simpson's car, the cost whilst still maintaining all the regulations and get good mpg / low emissions would make it very expensive. If you look at the markets for offroaders, the jeep is king in America, the Toyota is king in Australia and everywhere else just makes any old stuff work. There's no market for it in the UK. Companies either buy cheap, so that's a pick up with an old fashioned chassis they can bolt stuff to, land rover are never going to make anything for £16k it's not worth the production line space, or they buy for a purpose ie unimog, iveco 4x4 truck, sprinter 4x4 or one of the raft of other things which are more practical than than a car sized 4x4 for a utility environment.
There are lots of neat things they could do like easy to replace bumpers for when you clip them or even ones that come off for off-road and store on the roof. Or easy to remove rear seats leaving a flat easy clean load area but they won't. It'll be all about how many settings on the off-road dial and how well connected it is.
It will be a freelander based on parts they already have and branded a defender for marketing.
Let's face it though, if your hankering after land rover that you can tinker with on your drive and customise to your needs you've got 70 years of production to go at and for a lot less outlay than the new one will be.
