1) FTFY.
2) Why?
You keep bringing up purchase price and buyer age - why is that relevant?
1. It doesn't have to be regarding my point.
2. See the point you cross out.
3. I already noted why. A vehicle that is reliable as a grocery getter for a 60 year old in Florida might not be reliable for a 35 year old pipe fitter, because the use case is very different. If it was an outlier that would be one thing, but if it is the general use case for a vehicle because of the demographic that uses them, then what why would this not matter?
Would you expect a model of vehicle with large numbers of fleet ownership to have different mileage distribution numbers from a model of vehicles that are almost exclusively purchased and leased?
Would you expect a model of vehicle with large numbers of vocational usage to have different reliability figures from a vehicle that is largely purchased by an older demographic and doing little aside from moving itself?
I think the GX 470 is reliable by most accounts, both numerical and anecdotal. However, I have still not been shown anything that shows the the LTQI statistics could be used to compare vehicles across classes and their typical use cases.
Do you have any evidence to demonstrate the effects of vehicle classes and use cases on reliability? Do you have any evidence to contradict the LTQI results? Do you have an objectively better source of information from which to evaluate reliability information?
No evidence to demonstrate the effects of vehicle classes and use cases on reliability. All I have is thought on it. I feel like a Honda Accord, while highly reliable on LTQI, would have more reliability issues as a track car vs. a Corvette. Perhaps not though! I genuinely have no evidence on me to immediately show that. I have no objectively better source of information to evaluate reliability information, but that of course has nothing to do with whether or not it's beneficial to use information in a certain way or not.
I would love an MTBF- or long-term-TCO database to draw conclusions from... but I do not have that, so LTQI will have to do.
Using information you have available is fine, but again, I don't see where comparisons across vehicles from different use cases are particularly helpful.
Edit: I think that you're seeking some ultimate 'all variables normalized' reliability indicator. A noble endeavor, but perhaps not practically useful. Do you want to buy a beat-up van because when normalized for abuse it's better (in a certain sense) than a luxury SUV that's been babied? Or do you want to buy the babied luxury SUV? In other words: if the reliability index tends to favor un-abused vehicles, that's what I'd like to see!
I'm not seeking anything really. I'm not hunting for a vehicle.. I'm saying that just because an Index is being used for multiple vehicles and classes, it does not mean that the index is useful compared from one group to another. I will say that there are pages on the site that display LTQI scores amongst various vehicle classes. I would indeed consider that to be more useful, as the sample size is much more likely to normalize within the same use case.
