you can tell someone's age by the "mods."
under 30: ricer crap.
30-40: no tacky stuff, maybe a nice aftermarket radio, legitimate mods like power adders.
50 and up: chrome and vinyl/cloth tops.
yes, i'm joking.
kinda.
when i bought my Jeep there was an older couple that was buying a Concorde. i commented that my mom was looking at one and it was a really nice looking car...the wife says "oh, but we're having it sent out to have a fabric top put on it, and the portholes, and..."
hence my sig.
