DT reader JJ points to one of the first behind-the-wheel reviews of the new Mercedes "grand sports tourer" (the phrase will always have quotes around it, I fear.) at The Truth About Cars.
Even though it does a lot of stuff a minivan does, and a few things the M-class SUV does, and other things a cross-over does, TTAC doesn't say it's a minivan. It's apparently pretty good, which means it can't be a minivan. Right? right.
I think this can be cleared up pretty quickly: It you have an R-Class, it's not a minivan. And if you don't, it is.
There you go. You're welcome.
