There are quite a few things, but my Jeep is probably at the top of the list. I am far too attached to it and it is priceless to me, even if it is purely for sentimental reasons. It is only a 1996, but it is the first vehicle my parents bought brand new.... and it is the vehicle my dad taught me how to drive in. I remember sitting in the back seat of it that night we brought RB Frisk home for the first time when he was just a wee puppy. There are just so many good memories.....
