Well, I'm doing a full redesign, but... I was looking at the dimensions on the drawing & began to question whether my size 12s & 34 inch inseam would really fit, so I spent some time sitting in my MGB & 944 taking measurements, which convinced me there was no way I would fit comfortably. If I'm building something, I want to feel comfortable in it, so some things got stretched.
Been there. Also, you can never make both the design team & the production team happy at the same time. I've been on both sides, so now I'm arguing with & compromising with myself.
