Some alternatives, if you want some peppy amercan muscle without expensive insurance (and still chick magnets) 68-72 Cutlass supreme coup or 442, Buick Skylark, or Pontiac equivilant. These have just as much get up and are available in convertibles if that's your fancy. All are easy to work on and seemed to weather the years well if not rusted out.
