Of course, I have the diametrical response to the above.

I've test driven every model of vehicle I've purchased. If different powertrains/drivetrains are available, I A/B comparison those. I want to assess powertrain (clutch feel, if manual), suspension compliance, handling capability, steering response, go over the body with fingers feeling for under/overflush conditions between panels. I assess reach and sight-lines of interior controls and seat comfort.
A couple of decades+ at another OEM working as a product planner alongside engineers during development, in the pilot plant, and at final assembly was a valuable education. It would be impossible for me to buy any vehicle without driving it first.
