Widened wheel arches possibly making it less unstable and therefore more fun. Life's too short for regrets, but you could always get another. I had an MG Midget in the late 70s, great fun, but when I went back to college I sold it as I guessed correctly that I would not be able to afford the money or time to keep it in nice condition. The decision at the time was right, so I do not regret it. Lots of fun for 4 years to remember! Back before I made drums I had a kit Custom made by Eddie Ryan with a unique 15 x 15 inch floor tom so I could (JUST) get the whole kit in the car!
