Sorry to dig up this old thread, but this is a topic that interests me...
Disclaimer: I am part of GAP Diagnpstic. We make the IIDTool that Mike was talking about above (thank you, btw). As we are not sponsors here in the forum and I don't know what the forum rules are, I am going to speak in very general terms here. I am here out of personal interest and 'as a civilian', so to speak. But I am also a bit of a geek
I really don't feel like the OP's question is posed properly - or that the question needs to be posed at all: repairability and comfort are not mutually exclusive. And having electronics in a vehicle does not preclude the possibility of field repairs in any way. Yes, you are going to need more than the hammer, screwdriver and duct tape that would have been required for a Willys Jeep or 1960's Bronco, but you will not need much more. A small, portable diagnostic tool, some electrical tape and a test light or multimeter will usually suffice.
One good thing about a modern, electronic equipped vehicles is that, in contrast to older purely mechanical vehicles they will actually tell you whats wrong. And with that knowledge often anyone with even the most rudimentary mechanical skills can repair or jury rig a solution to at least get back to civilization. Not really a great difference to the 'good old days' where you had to know about fuel delivery, spark or how a diesel injection pump works etc before you were capable of getting yourself out of a situation.
The problem is not that the the repairability as such was beyond the skill set of an average Joe, but that the diagnostic tools and knowledge required was held back by the manufacturers to try to ensure a monopoly on service for their dealers (which never really worked out anyway). This has changed. For nearly every automotive brand and model there is a company such as ourselves (we only do Land Rover). And thanks to the internet, there is so much shared knowledge in forums etc that in many cases you can DIY a repair as quickly and easily as a trained dealer tech (and much more cheaply!).
And a couple of other points to ponder:
- in general, today's vehicles are miles more reliable than older vehicles. Really, miles more.
- it's not only comforts that the electronics provide, it's safety, economy, cleanliness, power etc etc etc (how many 1990's off-roaders are you going to find with more than 300hp or more stock?)
- depending on your needs, the electronics that come in the vehicles from the factory can more than compensate the need for a ton of expensive mods, such as lockers or a lift (with air suspension) etc
- electronics have come a long, long way since the 80's and 90's. Today's electronics are much more robust - and idiot proof.
There is literally no place on earth I'd hesitate to take even the most decked out, electronic equipped 4wd (such as a Range Rover). You do need to prepare yourself tho. And having the right tools and a little knowledge about what you are going to be doing is essential. As is having a set-up that suits your needs.You can set up a vehicle to play submarine and do water crossings up to sun-visor level if you like, but you need to do the prep first. And that has not changed. Water crossings on most older vehicles ended in tears at breather levels or at the latest at distributor levels if left stock...
And despite all of this, I am still a strong believer in the KISS principle
