If you know nothing about cars, I would HIGHLY recommend hiring someone to locate a car for you - once you've figured out which year you're looking for and what your HONEST budget is. And I would highly recommend that you buy a "done" version of whichever year you select.
You also need to decide whether you want something that's original vs having been cloned into something different than it was when it left the factory. If it's original it needs documentation and someone to validate the documents and car components, particularly if you're new to all of this. There are lots of thieves and con artists in our hobby. That's a fact. Things are regularity misrepresented. Fraud is always lurking. Given the money involved, it is critical to get an expert working for you, IMO.
We have a number of experts here. Model year specific experts. Mike Crown probably forgot more about 66's than most ever knew. Rick Nelson knows '70's. Personally I hired Rick to find my '70. Don Lightfoot knows '69's.
Orginality = $$ - but, as a general rule, is a better long term investment - if that's your motivation.
You can buy one done alot cheaper than you can have others do it for you. Trust me. I know!!
