Almost ever y car you’ve ever loved, loathed or desired is gathered under one roof at the Haynes Motor
Museum. Over 300 immaculately presented cars and motorbikes represent ever y aspect of our motoring
heritage, from elegant reminders of bygone days, such as the superb Model J Duesenberg to curiosities like
the bug-eyed BMW Isetta.  There are also many old friends and flames. Perhaps you remember the 1959 Ford
Popular that you did your courting in? The magnificent ‘Red Collection’ is a spectacle of classic sports cars
including AC, Alfa Romeo, Austin Healey, Ferrari, Lamborghini, Maserati, MG, Riley, Porsche and Triumph.
A Perfect Day Out
Each and ever y vehicle at the Haynes Motor Museum has played its part in the histor y and culture of
Motoring. Today, they make a wonderful spectacle and a great day out for all the family.  Bring the kids, bring
Mum and Dad, but above all bring your camera to capture those golden memories for ever. You will also find
an impressive array of motoring memorabilia, a comfortable 70 seat video cinema and one of the most
extensive transport book shops in Britain. The Pit Stop Cafe serves ever ything from a cup of tea to
wholesome, home-made meals or, if you prefer, you can enjoy the large picnic area nestled in the beautiful
rural surroundings of Somerset.
The Museum is situated on the A359 Yeovil to Frome road at Sparkford, just off the A303 in Somerset.  It is about 40 miles south of Bristol, and 
25 minutes drive from the M5 intersection at Taunton.
