Welcome to CHR! I've helped build a couple glass 32's before. Like Lynn said, you can do it for $30k but you need to have it figured out what you want to do first to keep from buying parts 2, or 3 times. And try not to change your mind during the build which leads to more cost and build time. I'm guilty of both.

I'd say you could do it in half of a 2 car garage. Is it going to be ideal, no. But there are guys on here building awesome rods in about the same space. Ideally the entire 2 car garage would be better. But it's a 32 and not a crew cab long bed truck here.

Also, how is the roadster in the last pic well north of $250K? Maybe if you pay a high dollar rod shop to do every nut and bolt, stitch, and air in the tires?
