Here's a couple picks my mom emailed to me. The yellow one is a Continental kit; a bumper extension and spare tire cover to make any car look like a Continental. The other is a fender skirt on an older car.
Looking at those reminds me of my old 91 Caprice that had the half skirt on the back. That car was awesome and got good mpg to boot for being, at the time, 12 year old car with a tbi 305 in it. There are some pictures here of it along with my regal. http://www.cardomain.com/id/ophidia31 My friend always said it look awesome with the way the water came off it driving on the highway when it was raining. Had plans for a rear lip spoiler and airdam on that car before gas prices skyrocketed. Ah, memories.
