They're pretty common in the SF Bay Area, where non-work trucks are very uncommon. I wouldn't expect to see them in places where using a truck as a daily driver is normal.
I actually really want one and could afford it, but the combination of abundant apparent QC issues and reports of poor/slow customer service kill the idea for me.
Once they’re out there for another couple of years and there are published statistics - and I’m able to get my hands on some used ones to see how they’ve held up - I’ll reevaluate. Until then, I’ll stick with my 25-year-old Jeep.
