I take it you never drove a classic Mini......I swear I pushed them more than I drove them......
First car was a Hillman Imp, pile of faeces, aluminium cylinder head warped so many times it was unbelievable. Easy fix mind you!
That was the only car I had prior to my shed load of Fiats that gave me any real grief. Many VW cars, mainly Mk2 Volkswagen Gti models, and any problem was an easy roadside fix with the aid of my ever expanding toolbox in the boot. Only cars that have ever left me stranded have been my recent Fiats, and an early 127 Palio (pile of excrement).
