I can remember for the past 20 years, people have been talking about how technology would make cars unserviceable. When they switched from carbs to basic fuel injection, the world was supposed to end. Then when OBDII came along, look out!
The way I see it, things have never been better. One can buy a code reader for $100 that can give you insight into what's wrong with your car instead of fiddling about with points and floats. For $500, one can buy a computer flasher for the more popular models that allows you to completely retune the engine without mucking about with recurved distributors and jets.
The only people who have been left behind are those who are afraid of change.
Sure, the LR3 looks complicated now. And it is... but it's also been made with vastly better engineering resources and materials. It has a lot of systems, but once the price comes down and home mechanics start buying them, I hope that affordable diagnostic systems will be available.
The only threat to my view of things is the OEM's desire to make things proprietary in order to force people to return to the dealer for $ervice. They must realize that no matter what... people with money will not be buying used cars. And you have to have money to maintain an older car if you are going to go to the dealer. I mean, who in their right mind would buy a 3 year old car for half it's value, but then spend $1000's every month on repairs at the dealer? If I had that kinda cash, I'd just buy a new one with a warranty and service plan.
That means they have to accept the fact that it's people who will be fixing their own cars who will be buying them at the end of the lease. The more complicated you make them to maintain, the less appeal there is for us, and thus the value is lower.
This is why the complicated fancy cars plummet in value no matter who's name is on it. It happens to all of them, MB, BMW, Audi, etc. This drives up the cost of leases, or makes the purchase decision more difficult because resale is so low. I hope they figure this out soon.
