Welcome to Stevenson's Motors
Morris Minor - Restoration, Modification and Enhancement
Stevenson’s Motors has been a brand that has brought outstanding knowledge, quality and attention to detail since first opening their doors to the public in the early 1980’s. Early on we concentrated on restoration work, but it was always clear to us that modification was vital in keeping these cars on the road and getting them to appeal to future generations. Based in the heart of England we have never been short of a testing ground for these enhancements and through working closely with a world leading ST team we have had a busy few years getting our test car to a level we are happy with.
What 2010 brings ...
Stevenson’s Motors is busy building a prototype car, comprising of enhanced safety features, up to date engine and drive train, intuitive interior features and heavily tested handling capabilities. Whilst we are eager to get the “GT” finished we are open as usual with plans to have the prototype finished before the end of show season.
We are currently working on...
