Id have bought a stripped out solid axle G professional in a heartbeat, if they charged a reasonable amount for it. However it was never offered to us in the UK, and it was stupid money. I know they're well built vehicles, but for what is essentially a 30 year old design, with absolutley no mod cons, it was way too steep.
As for the new professional trim, that seems like an exterior package, and is at the other end of the spectrum luxury wise. its too much, i dont want an S class interior, just somewhere decent to sit for 10 hour road stints.
The Grenadier is the vehicle that splits the difference, whilst also coming in cheaper than both of the Mercs. its more comfortable than the old G, whilst having enough modern safety and creature comforts.
Id love Merc to prove me wrong and pull out a sub 60k G wagon with offroad hardware and modern pickup levels of comfort, but i cant see it happening!
