‘Myf” is a 1973 MG Midget (US Spec). In 1990 Geoff Foster purchased her and built her into a race car. Geoff campaigned her around many of Victoria’s famous tracks until November 2000.

Steve Jones purchased the car in a very sad state in December 2007. She went into Steve’s workshop and underwent a full restoration. The car was completely stripped and the body sandblasted revealing an extreme lack of bodywork (rust). New inner & outer sills, A-pillars, footwells and lower rear guards were either purchased or made. Although the basics were there, Steve re-engineered a number of areas including the doors, boot, interior, wiring, engine breathing, front and rear suspension.

Every component was checked and repaired/ modified or replaced. Steve and a few mates did virtually all the work in Steve’s shed. The car was painted and after 12 months work, she had her first test run on a closed road. Here first race meeting in Steves’ hands was at a GEAR meeting in December 2008 where she instantly showed her potential. Since then Myf has competed at:

  • Oran Park (GP) – 1′:26″:93
  • Oran Park (south) – :52”:69
  • Wakefield Park – 1’:11”.63
  • Eastern Creek – 1’:55”:38

  • Ringwood Hillclimb (long) – 42″:64
  • Rob Roy Hill Climb – 26″:02
  • King Edward Park Hillclimb – 44”.04
  • At the 2011 MG National Meeting in Newcastle NSW, Steve and ‘Myf’ took the outright Hillclimb as well as outright Motorkhana trophies
  • Took the 2014 Australian Hillclimb title for Marque Sports < 1600ccat Ringwood Hill Climb (long)
