Adam took a bus to Chattanooga and drove Fiona home.
She's been enjoying the zippy life of a college campus, but in reality, Fiona is an old girl, born in 1986. College life was a bit much for her. She's had a few problems (some from, ahem, driver error), and Adam will be fiddling with her and making her all perfect again.
If you're interested in owning a beautiful 1986 Jaguar, let me know. We'll be selling her soon.
