The date has been set for the 2013 Classics in the Walled Garden event at Luton Hoo.
The show on Wednesday 10 July will be the event's 5th running, with last year's outing attracting 650 cars and raising more than £2000 for good causes.
Spaces to show cars are allocated on a first-come-first-served basis with the first 150 inside the walled garden itself, the next 150 adjacent and the rest in a nearby paddock.
If you want to sign up, be quick: in 2012 the 150 spaces inside the Walled Garden went within 24 hours of the event's launch.
Vehicles should be more than 20 years old to qualify, though some modern classics may be admitted at the organisers' discretion.
There will be music, a licensed bar, and catering, but strictly no entry to the event before 4pm.
