I don’t really know what I’m doing

Nice to hear of someone younger taking an interest in these cars!
There's an incredible amount of knowledge that's shared on this site every day, by some awesome people! I've learned a great deal on this site in the last year, it's awesome.
My advice to you, is if you ask a question, include as much info in it as you can, and pics always help.
Nice car! As for the roof color, I've always hated vinyl roofs, and different color roofs... I like plain body color better. But in the end, it's your car, do whatever YOU like.
