What's a locking glove box? Wait... I think I had one in my 1971 Cougar.
So I post a response and it does not show up Hmm forgot to log in again.
But back to the subject.
Had a locking glove box on my 67 AMC, 73 and 84 Audi, I think my wife had one on her Suzuki but nothing since including SAAB, MBs, or the Disco. With present remotes having the emergency key hidden away inside, a lockable glove box is not practical. Besides if you hand your keys to a lot person or valet they would have the glove box key as well.
Things in my glove box, pens with or without ink, paper, wipes for the grandkids, insurance/license paper (combined where I live), old candies?????, receipts for gas and hotels when on a trip, some old business cards and the owners manual. Merc had a nice hidden place to hold manual in the rear of car which freed up room for junk. And oddly despite living in a cold country I have never had gloves there. Oh Diabetic sugar pills in case I get dizzy while driving, but the grand kids have a fondness for them.
as does the wife!
In the special hidden spot that we all know about near the cup-holder (That should never be talked about)
I keep my Nexus card so I do not need a passport to cross speedily from the US to Canada or visey versa.
Wish that I did have valuables anywhere.
