I was up at the Roadster Shop facility back in March to check on a a chassis I had on order. I got the full tour of the facility and they were bursting at the seams!! Even with as many cars as they had going on I'll give them credit and say it was organized chaos. Everything had a place, everything was in a line, everything had paperwork attached. They had to have close to 40 cars in some stage of build not to mention at least another 20+ chassis in process. They had chassis stacked on racking up the wall just for space!! Are they suffering growing pains? Maybe but if so they hide it well! Everything I've seen on that floor and finished product has been top notch and I'm not easy to impress. They delivered my chassis about two weeks later and its beautiful. The welds are so good they look machine quality.
And I'll second the notion that good shops will always be busy. Look at how many of us boutique builders here on this site have more work than we can keep up with with most of it fixing cars built by other people. For them to be building custom pro-touring muscle cars is tough enough; for them to be doing it at a production level and keeping the quality and timelines in check takes an inordinate amount of organization. My chassis was done within a week of their promised delivery date given 12 weeks earlier.. that is amazing for this industry.
If it wasn't so damned cold up there I would have probably applied instead of reinvesting my whole life in the new shop. I love pouring through their build pictures for ideas. I'll put my name in if they ever want to open a "Roadster Shop South" down here in TX.
