Hi Steve, here is what John Riley said in a 1971 interview about the two Mustangs. He still owned the Fahey Mustang at this time, but had raced the Geoghegan/Coppins Mustang in the 1968/69 season:

"Its (the ex-Fahey Mustang) a nice car to drive, far better handling than Rods (the ex-Geoghegan Mustang). It goes through a corner so much quicker it isn't even funny. I used to wonder how two comparable cars (Rods and Pauls) could be so far apart on the track. Paul was always so much quicker. In the early stages when Rod first bought that car I thought it must have been Rod himself, but since I've driven the two cars myself..... The difference in unbelievable. The Fahey car had wider wheels, and probably a lot more work done on the suspension. The motor was better also. The Coppins motor had a very early model roller cam which used to make a beautiful exhaust note but it never had the same torque or power as the Fahey car. I like driving Faheys car however. Its a good car".
