This next car comes from tipper Jeff who writes: The only IROC i ever knew of was the Camaro! That's right, the IROC (International Race of Champions) badge is normally seen on Chevy's Camaro, but Dodge also used the badge on their Daytona and it was very similar to the Shelby Daytona with a 2.2 liter turbo-4 putting 224 horsepower to the front wheels. Find this 1993 Dodge Daytona IROC offered for $4,500 in Detroit, MI via craigslist.
The last time I posted a low mile Chevrolet Camaro and had the gall to insinuate that the 3rd gen F-body was not yet (if ever gonna be) a collectible, I got the brunt end of some IROC hate. Today, I'm not going to make that same mistake, and I'm only going to say nice things about this mullet-mobile. Ooops. Find this 1987 Chevrolet Camaro IROC-Z here on eBay bidding for $10,107 with 1 day to go. 
When you think of Pony cars from the 80's and 90's the Dodge Daytona probably doesn't come to mind. Camaro Iroc Z's duked it out with Mustang 5.0's for king of the street during this time period. Dodge slyly took over as primary sponsor of the IROC race series in 1991. The Daytona IROC R/T model ran from 1992-3 similar to the Spirit R/T sedan which shared the same 224 hp turbo drivetrain. Twenty five years later, one could definitely make a solid argument that the Daytona and Spirit R/T models were ahead of their time and a look into the future.

Wedding season is overspending season. We're obligated to lavish the young couple with matching "bride and groom" keepsakes of sentimental value simply because the registry says so. Not even in rural Sullivan, MO would you find a bridal registry including two matching turbocharged Dodges old enough to legally toast the happy couple with Walmart champagne. However, these two Dodges, listed separately but sold by the same seller, are tempting for the creative gifter. It's the thought that counts. Find this 1991 Dodge Spirit R/T and this 1992 Dodge Daytona Iroc R/T for sale in Sullivan, MO for $2,500 and $3,500, respectively, via craigslist.
