I looked at both cars & here is all the wisdom I can offer:
1. Both cars look pretty impressive.
2. Big difference in price & year, and I don't know what your budget is.
3. The 1970 is in LA, which is only 5 hours drive for you, to look at it.
4. The car in Florida looks mighty fine with that low mileage ( if true ).
In any case, the normal advice applies here.
Have them checked out by a trustworthy mechanic, preferably before you make any final commitments.
Sorry I don't have any more ideas at this moment.
