That would be a fair comparison because they're both SUV's. Comparing a Toyota IQ with a Bentley Continental isn't a fair comparison, like that warranty company mentioned earlier in this thread does (An IQ shouldn't be on the same list as a £100k+ car, in my opinion). Put the top end luxury cars on one list & your small city cars on another - That's my personal view.
Number 1 on the list on this website

is a Toyota IQ (a small city car) & towards the bottom of the list are top end sports cars like an Aston Martin DB9 & a Bentley Continental GT. Yes, you'd expect your £100k car to be reliable, but there's much more to go wrong that when it does, it costs more to repair because its a top end prestige car... A Toyota IQ isn't. Based on that, they (top end cars) get marked down for reliability because they cost more to repair than the little Toyota. There's ten times as many things to go wrong (literally) & these luxury cars cost ten times the price. Who would have thought that a Bentley would be more expensive to repair than a Toyota IQ, or may be less reliable?
Cars with complicated electronics all have the same issues. BMW, Bentley, Rolls Royce, Land Rover, Mercedes... That doesn't mean you put them on a list with a car that if you're lucky has electric windows & central locking.
I'd be annoyed if my Toyota IQ cost as much to repair as my fancy Bentley. Being a small city car with literally no complicated electronics, air suspension etc, I'd expect it to be reliable because there's hardly anything to go wrong (You can just about fit a bag of shopping in the boot). Again, that's why I say small city cars shouldn't be on the same list as a top end prestige vehicles.
Lexus always have been, certainly for many years, considered to be the pinnacle of reliability... yet there's hardly any on the roads? Don't be fooled though, they cost a fortune to repair when things do go wrong (Which does happen, as they won't last forever without some kind of hiccup).
You'll count multiple Mercedes, BMW's etc on your daily drive, but hardly any Lexus... Odd, but true. That seems weird considering they're so reliable, but I think its because there's very few diesel models (Apart from the IS as far as I recall, possibly one or two other models) & that wasn't particularly reliable either from what I've heard. So people looking for an Lexus IS sized car go for the more desirable BMW 3 series, or C Class Mercedes (both drive better than the IS actually & outsold the IS by miles). Lexus mainly stuck to big cars with big petrol engines = not affordable to run for most people. Hybrids of course is another forte of theirs, but again, they (Lexus Hybrids) aren't particularly popular either. Another let down is the CVT transmissions that they put in their vehicles. Yes they're incredibly reliable, but have you heard the roar they make at motorway speed? That is not what I expect from a luxury car.
