P38 is probably "peak long term / classic 4x4". Basic underpinnings are rock solid. All the weaknesses are known and relatively sortable. Its a really nice drive too. Biggest issue is thirst but thats helped keep the supply of low enough mileage ones to be worth grabbing reasonable. Be nice if an 8x4 sheet of ply would fit inside but hey you can't have everything.
L322 won't cut it. Stupidly complex and fundamentally unreliable on the electronics. Hardly surprising given its a mash up of three different systems. Hard to work on. Corrosion prone. Already into issued with unobtanium can't be fixed or work around issues like steering columns. The amount of problems herladyship has had with her TD6 are unreal. So glad she lives 80 odd miles away out of range of "can you fix it" calls. She is now going into run it into the ground mode before getting a later model. Which really worries me!
I told her to get a P38 on LPG but would she listen. Got her (and puddy cat) staying for a long month from 1 st November so I guess she is getting the keys to mine for re-education in what good car is. If she converts it will probably end up costing me £6,000 to build her one good for 100,000 miles but almost worth it to save ear ache of my cars gone wrong calls on a near monthly basis!
Wouldn't touch a BMW V8 with barge. Several can't be fixed issues put you on borrowed time once over 150,000 at best. Same with gearboxes.
The Rover V8 may be old tech and thirsty but its repairable for not too silly money. Never understood why Leyland didn't slap modern 4 valve heads on to get the thirst down and power up. Relatively simple to do and the pushrod / OHC thing is a non issue for normal road cars. OHC on everything has more to do with manufacturing processes and fashion than technical advantage at sensible RPM. The man who invented the timing belt has a lot to answer for.
