@mike I asked at shop (a two-man show that has been a great experience so far on every level) for what they'd recommend for a minivan out of curiousity (we're currently driving a 2017 Kia Sedona).
He said new or used, the Toyota is his recommendation for best value for the money and that with proper care, he's seen them (the basic gas engine versions at least) go 400,000km.
I recently compared all the minivans available brand new in Canada, and if you add purchase price plus cost of gas, the Toyota (only available as a hybrid here) becomes the chepest van after about 200,000 km of driving. Cheaper than the plug-in hybrid Pacifica!
@sabbatical @mike My guy said Honda would be his number two, even though they are more costly in msrp+gas than vans he likes less, because of things like maintenance cost and resale value
