When my dad had his 81 someone stole it, took the rims (the stock ones... this was in 96... wtf..) and took the stock 8trac radio that didn't work anyway. Drove it like a parking lot away (still in plain site) and left it with I think 13"s. Just plain lame.
On another note, my friend recently had someone break into his Mustang. They ripped his aftermarket oil pressure gauge off and unscrewed his A-pod gauges but couldn't get them out so they went next door. Tried to come back the next night and my friend's dad saw them, went out and caught one, the other one bolted, he whooped the living day lights out of the one that didn't and called the cops. Little punks all over the place today
EDIT: Mustang is a 90, interior is in bad shape, has a 4 banger in it from a T-Bird... Wtf there as well
