the reason we can't get basic non electronic vehicles in this country is because of emissions regs. The new euro 6 standard means it'll be pretty much impossible to even run your vehicle outside Europe because of the fuel requirements.
The reason these basic vehicles are so expensive where you can get them is because of the build quality, quality costs I'm afraid and that's why cars like mercs and I would suggest the newer hilux like I have are not as well made as, for example, my HJ60 which appears to be made to lorry standards, overengineered to the point of obscene!!. As long as customers keep dumbing down to the lowest price rather than looking for the best quality that's going to be the way. Fleet buyers, the main market for vehicles like the Hilux, aren't interested if the vehicle lasts 25 years because they are on 5 year contracts, and they aren't interested on the better residual value of a better vehicle because at the end of the contract they just swap them out. why would a fleet buyer buy a Hilux that was beautifully engineered if it costs 5k more than an L200?
I am sure there would be a limited market for a good basic vehicle amongst expedition users etc who would be prepared to pay the price premium but unfortunately in Europe the regs make it impossible
