As a native Tennessean, I can say you could not find a better (color coordinated) car for a UT Volunteers fan. 1977 Oldsmobile Ninety-Eight 49K PRISTINE SURVIVOR 98 REGENCY 6.6L 403 V8 4BBL | eBay
$18,000 is pretty steep for that, but the seller is a dealer. 49,000 miles is low but not that low. Nice car nonetheless.
This dealer buys a lot of cars off Craigslist and Facebook and sells them at huge markups. Most cars are nice, low mileage cars. This particular car was listed some months ago in South Georgia for about $6k as I remember the ad. A good cleaning and paint correction yields a massive profit. He bought a rare Crown Vic Touring Sedan that I was looking at on Facebook for $5k and listed it on his lot for $15k.
