How do you verify car mileage?

I just bought a cheap used Jeep Grand Cherokee but it needs a bit of work. I’d like to start by scanning for error codes, but I can’t find the data port! Can you tell me where the OBD port is on a 1995 Jeep Grand Cherokee?

My car’s been acting a little funky lately, and my neighbor loaned me their OBD reader. But here’s the thing—I don’t know where to plug this thing into. Where is the OBD port on a 2016 Honda CR-V?

I’m moving to upstate New York, and I’ve had several people there tell me about Subarus and how great they are in the snow. I’m looking for a used one as a winter car, and to occasionally take camping. What’s the best year for a used Subaru Crosstrek?
