Their being higher is a big factor I bet (less stooping and more road visibility, although the latter is less of a factor as they get more popular).
Reminds me of the bumper sticker I saw on a big, jacked-up American truck, though: "If you can't stop, smile as you go under."
Well yeah...they might be a thing that fits well in the US but they as sure as hell don't belong in Europe.
Reading this thread and seeing all of the reasons people come up with to justify their "need" of a truck is hilarious.
I live in the midwest, have to deal with snow, and with a good set of winter tires I do just fine in my 97 na.
With my big pickups, I just try to center the deer on my massive grill guard so they don't dent the quarter panels.
Also, realistically I don't think sitting slightly higher up gives much better visibility.
What about the rest of the time though?
Would you save money by using a "normal" car for most of the year, and then renting something bigger (SUV, (mini)van) when you need the large volume? Or purchase a hitch for your car and rent a trailer when you need to haul things?
A co-worker of mine drives a Ford F-150 year-round because he owns a fishing boat that he used 5-6 weekends per year. Seems... sub-optimal.
A bigger car of a non-premium brand with a small engine would probably cost about the same in taxes, insurance, consumption.
F-150 is total overkill of course.
An Audi Q5, for example, is big vehicle, yet I've more space in my 3 Series GT. Very similar story with the BMW X3 and the Merc equivalent.
At some the very biggest SUVs, such as the Q7 and X5, yes, you have a decent amount of space - but it's absolutely less than you'd think for what are basically tanks.
Brussels - Bilbao at the end of Dec is 1500EUR for 3x tickets. Driving there & back is around 5-600EUR, including diesel, tolls and a cheap hotel half way.
There's cheaper tickets with budget airlines but getting to some rural Ryanair airport by 6AM with a toddler and a baby, no thanks.
A car like this should be able to do 80K Km before needing any serious maintenance / repairs so a 2500Km round trip doesn't worry me too much. It is indeed also about convenience.
Flying somewhere for vacation now costs $$$, so driving say to France, Spain or Portugal is a lot more appealing. A baby stroller already takes up half the 500L boot/trunk space of my BMW X1 and even with an annoying & noisy 400L roof box we still can't fit everything we want (I used to go backpacking for months with a 35L pack, so I'm not someone who takes the kitchen sink on vacation).
A Skoda Superb has a boot space of around 600L, one of the largest among "normal" cars. If you want more space, I guess you have to go for something that may look out of place in the city center but does have practical appeal even outside of farms.
