Trying to finally get my first Muscle Car - I’m nervous

When I bought my car, I sat down & figured out what it would cost to get a bare bones Demon body to the point that I bought mine (rolling race car). I based all of the costs on purchasing the parts already on my car, & not counting the welding, body work, & paint. I came up with a 5 digit figure, 20k+. I paid less than half of that for the car in my avatar picture. I won't go into the details how how much & what was on the car but I'm sure if you think about 20K it can be figured. As of today, with all I've done since the initial purchase, I have well over 30K in it, I will never see that kind of money "if" I ever decide to sell.
