Grenadier Longevity?

Hello community!

I am considering buying a Grenadier in about 2 years as a company vehicle. The single most important thing for me is longevity. If I pay this amount of money on a car I want to use it for at least 15-20 years, in an ideal world I could give it to my future children in decades. Ok, I know this is probably too much to ask for in a 21st century vehicle but it looks like the Grenadier is the only one I could get in my country that could even remotely be considered for such a long term use. Sadly, LC 70 series can not be bought or registered in my country.
I want to buy quality tools that are build to last and certainly not throw away products that have to be replaced every so often. Most modern cars are the latter but what about the Grenadier?

From the things I looked at, the Grenadier seams to be constructed very robust, with many parts actually being overbuilt. Frame and suspension looks good to me for a decade long use. But is there anything that could potentially be its Achilles heel?
What are your takes on the engine(s)? While I am a great fan of older BMW engines and have total trust in these (M20, M50) I am not so sure about the new ones. I´ve heard many terrible stories about new BMW engines, that they use a lot of plastic parts (eg plastic oil pan, who tf thinks this is a good idea?) that are designed to break right after the warranty expires etc.
Having dozens of ECUs in the vehicle isn´t particularly reassuring either. But I know its a 21st century car. Will these be replacable in maybe 20 years if 1 fails? Probably not. I have this problem already with my 90s Range Rover. If the ECU fails, the car is basically scrap, no replacement for it and no one can fix it. I am a bit scared of all the gremlins these computers will breed out further down the line.
How is it to work on? Are all the important components "easy" to reach and replace? Can the engine be pulled from the vehicle without removing the body from the frame?

Naturally, parts availability will be a major role. We don´t know if INEOS as a car manufacturer will still be around in the future. But then again... try buying spares for basically any old or classic vehicle from established makes... so it doesnt matter if Ineos still exists or not if I cannot buy spares for a 90s bmw either...


I know that the Grenadier as a car is not around for long enough to really tell anything but many of the parts used in it are.

So what are your expectations on the Grenadiers longevity and long term usabiltiy?
 
My thoughts...

The B57 and B58 BMW engines are some of the best around, certainly more durable than most.

One of the challenges with modern vehicles is the sophistication required to satisfy customers. When I was a kid 250bhp was supercar territory, now we get that from a diesel 4x4.

The Grenadier is indeed solidly built and should last decades.

ECU's are a challenge. Actually most are repairable, it's just that €700+ is more than most owners are willing to pay for on an old vehicle.

The mechanical layout means they are easy to work on. None of that V6 turbo nonsense where the body has to come off.

The biggest risk long term will be accident damage and getting the parts.

Will you kids want a dinosaur in the 2040's? By then an EV will do 1,000km on a charge and will need as much maintenance as a flat screen TV.
 
On the plus side.
The chassis and body work are well protected from rust and have a long warranty. I have added extra protection to mine and I can already see that after 2 years it was worth the effort and small cost.
The engines are under stressed and with regular maintenance should last a long time.
It's the type of vehicle that will (you could say has) develop a cult following, this bodes well for getting second hand parts and accessories. and also aftermarket parts.
Many parts such as some of the steering and suspension components could be fabricated by a decent workshop... it's pretty agricultural like that.

The N series engines were known for that sort of thing. The B series is now a decade old and is known for being very reliable. Plus, the ineos version is detuned to improve reliability. A lot of people spouting out about BMW engines just haven't updated their knowledge or understanding.
