do you use videos when restoring cars?
It depends on the car. Sometimes I'll use YouTube if I'm restoring something that's extremely rare or obscure.
Was the Alfa Romeo one of the sports sedan?
No, it was a Spider. It turned out beautifully! One of the prettiest roadsters ever made, in my opinion.
Was it one of the 1985  Alfa Romeo Spider ones or was it earlier?
Even earlier. I did an 80s Spider about six years ago, but for this project I restored a Giulia Spider from the 60s.
Knowing the authenticate or fake Alfa Romeo Spider is sometimes a challenge
That's true, and a lot of people get stiffed. I always have my buddy take a look at any project I'm considering. He's a professional auto appraiser, and specializes in vintage cars.
There is a Classic Alfa website you can get part for your car if needed
I might sell it once I'm done fooling around with it, but for the time being I'm having way too much fun!
