More than 600 classics are expected at The Gloucestershire Steam & Vintage Extravaganza at South Cerney Airfield from 2-4 August.
The charity event started as a small village show, but this years will attract more than 15,000 visitors.
Organisers pledge the classic car section alone will boast veteran, pre-war, post-war, American and modern classics.
Rarities expected to attend include a 1953 Kaiser Manhatten, 1958 Studebaker Golden Hawk and a 1957 Ford Skyline with retractable roof.
Here's some photos from last year and an idea of what you will see in 2013.
