The event, which has taken place annually in recent years, will return on June 28 with more than 200 vehicles expected.
The show will stretch across the town centre and Lowndes Park with supercars, sports models, and standout motorcycles on show on the High Street.
Lowndes Park will play host to car clubs, British military vehicles, dealership stands, and food vendors.
The event is being sponsored by Warranty Solutions Group, which is supporting the show for a third consecutive year.
Ian Tallent from Warranty Solutions Group said: “We’re proud to return as headline sponsor for the third year.
“The Chesham Motor Show brings together the local community, car enthusiasts, and families for a day of excitement and celebration.
“With so many amazing vehicles on display, our STORM Battle Bus and interactive experiences, and a few surprises we have planned, 2026 is shaping up to be our biggest and most engaging year yet.
“Supporting a meaningful local charity alongside the event makes it even more special.”
Visitors can explore a wide variety of vehicles, including classic, modern, sports, supercars, hypercars, and motorcycles.
Public entry is free, with voluntary donations collected in Rotary Charity buckets.
Vehicle display tickets cost £13, with proceeds supporting Chesham Valley Rotary and The Not Forgotten, a charity supporting veterans and wounded service personnel.

The company says it is also helping to raise awareness for the Children’s Memorial Garden.
Special exhibition vehicles confirmed for the show include a 1964 Corvette Sting Ray and a 2011 Bentley Continental Supersports.
Car clubs will also be out in force, with the Bucks & Herts region of the Jaguar Enthusiasts’ Club taking part.
The club represents Jaguar, Daimler, and SS vehicle enthusiasts across Buckinghamshire, Milton Keynes, and Hertfordshire.
Organisers describe the show, which will run from 10.30am to 4pm, as “a true family-friendly occasion”.
Last year’s event saw the town broken up into sections for different types of cars with American Cars in Market Square including Corvettes, Chevrolet, Cadillacs and Mustangs.Â
Various supercars and special cars were based at the war memorial with Ferraris, Lamborghinis, Porsches, Lotus, Daimlers and Bentleys.
Attendees later commented that the event had been ‘so well run’ and described it as a ‘great event, and an excellent turnout’.Â
