Sounds Of Summer Nights Favorite: 1989 Ford Mustang GT
The Sounds of Summer Nights always brings out an impressive lineup of rides, but few cars capture the vibe of a warm summer evening quite like Karsten Shelburg’s 1989 Ford Mustang GT. A true Fox Body Mustang GT time capsule, this car doesn’t just show up – it steals the spotlight.
A Fox Body Family Legacy
Karsten’s GT isn’t just a cool ride, it’s a family heirloom. Originally purchased brand new in 1989 by his grandfather, the Mustang was carefully maintained and driven sparingly, racking up just over 10,000 miles before being stored in a garage in 2001.
“I take very good care of this car – it’s got 12k original miles, and I’ve only put about 1k miles on it in the last 2 years.”
– Karsten Shelburg
An All-Original 1989 Ford Mustang GT



After Karsten inherited the car, it needed just basic servicing to get back on the road. Now, with just under 12,000 miles, this classic Mustang summer car remains completely original – from the Ford Mustang GT V8 rumble to the white leather seats that look untouched. The convertible top? It’s only been down three times since 1989.
“Nothing on this car has been changed – it’s all original.”
– Karsten Shelburg
A regular face at car events, Karsten uses the GT as a weekend cruiser and showpiece. It draws attention wherever it goes, especially thanks to its custom license plate: MUSICS – a tribute to his grandfather’s last name. From the moment it rolls into the lot, Karsten’s GT brings a surge of nostalgic summer car energy. The Fox Body’s unmistakable lines, originality, and great spec make it the perfect pick for retro summer night drives.
