I was the same, except Dad knew more than me, so he'd catch me out a couple times, it was easier in the old days to get the year and make from the rearends, since they changed almost yearly. Remember Caddys would change the front and back every other year after '61, just slightly tho, first the front would change, then the next year the rear, that would be similair, then change the front etc...
You should've got the Porsche 912, it was a 4-cylinder, had less power than the 911, but was better balanced, increadible handling on those, they used to sell very cheap, because people went, Bah it's a VW in the back, if they'd taken the time to really drive one on a twisty road tho
I almost bought a Z when I first moved down here, but it was from NY and was a little rusty. I looked hard at a '67 Cougar with a special order 351 Cleveland, fully documented. The seller painted Mercedes for a living, this baby had 10 coats of hand rubbed Wimbelton White, not a hint of 'orange peel' anywhere, Dark Red broquade interior, for only $3,500 Firm. Dad wouldn't loan me the extra $500 I needed for just another old car. He almost died that night
!! I saw the same car sell at Barrett-Jackson 3 years later for $27,000 and it had a couple chips in the paint, you can't touch up a muti-coat hand rubbed paint job properly, it never looks right. That was 'The One That Got Away' for me
