Panel List
In case it helps others, I'm going to be fairly open about costs (without disclosing information that is confidential to those working on my project).
Here's the list of panels I've bought, all from Porsche except a couple of repair sections from Roger Bray. Ordered well in advance of metalwork starting, because supply is not always perfect, but that also means pre-blasting.
Total cost: 5721.35 British Pounds including VAT (our sales tax).
Hmmmm.
