I've always just locked the center console and glove. I just put a soft top on and I don't bother locking the doors anymore anyways. I plan to get a locker for the trunk. This will definitely be the tidiest car you've ever owned because you'll never keep much in it that can't fit into a locked compartment.
I've had a bike bag, or groceries in the back that I've left unattended. My finance and I just go by the rule if we have something in there and someone steals it then they must have needed it more than us
. I just never keep anything in there that I couldn't afford to lose. So far I haven't had any issues. I get more worried sometimes with a manual that someone will pop it into neutral and take the parking break off; if they really want to mess with it, but so far no issues.
