More than 150 MGs, ranging from 1920s models to modern MGFs, will be on show in West Sussex on 28 April for the MG Owners’ Club’s Annual Rally.
Rare examples set to attend include early PB and PA sports cars, saloons from the 1930s and ’40s and a number of T-series models.
The event will also include a picnic, tours of the castle and the chance to climb its Norman motte.
Castle manager Bryan McDonald said: “We are delighted to welcome the MG Owners Club back for 2013 and are eagerly anticipating seeing what models cruise into the castle’s grounds this year.
“The club’s display of wonderfully preserved vehicles is always extremely popular with our visitors. Equally, the MG owners enjoy exploring the millennium of history that the castle holds."
Entry to the rally starts at £8. Find out more on the venue’s website.
