Keeper (noun) definition: "everything I own" pretty much sums it up for me.

Bought my first pin in 1994 and my sixteenth pin in 2014. Have never sold or traded any.
Bought my first electric guitar in early 1965 and my ninth in 2014. Still have all of them.

I have saved up for and then ordered five new cars since 1995 and I still have them all:
'96 mystic paint SVT Mustang Cobra with 7 miles on the odometer
'01 mineral grey SVT Cobra (with '03 Mach1 factory shaker hood added) with 55 miles
'08 torch red with black stripes Shelby GT500 with 9 miles on the odometer
'13 inferno orange with exposed carbon fiber hood insert Camaro ZL1 with 8 miles
'13 gotta-have-it green Mustang Boss 302 with 13,500 miles (daily driver in good weather)

Now that's an 8-Ball that really does look Deluxe!

Money well spent. You didn't Kiss that money goodbye.
