You guys have not started yet! This July I will celebrate 28 years of ownership of the '71 Sport. I bought it way back in ninteen-hundred and seventy-seven [cackle- I am in that 5 per cent age group from the age survey posted a few days ago....]. Second owner, all original, for the most part. Been from Cape Cod to Salt Lake to LA and points in between at one time or another.
My wife bought her '73 in 1979. So that is a score for 26 years there.
Both are now our primary (meaning "only") vehicles. Don't need anything else. Broncos are just fine.
And I know and have removed, fondled, and probably re-painted or upgraded EVERY bolt and EVERY original piece on the '71...at one time or another.
