Debating on A Body or B Body for first car

Hi, Everyone

For the past few months ive been looking at cars daily, wishing i had an old mopar just like my dad. But im really having trouble deciding on what car i think i should get, I was looking at dusters for a very long time and then i looked at a 73-74 Roadrunner or Satellite. Im only 13 and i know i have a good amount of time until i do get a car but i really am having trouble trying to decide what i want. And theres other cars i like too that i might want so these arent my only choices.

Thanks,

Joe
