Not as bad as it looks.
the accident damage is a nuisance, not sure if Mk3 bonnets are available, may need to graft bulge into a new Spitfire bonnet.
Front of roof a tricky fix. Sills are easy, though panel quality is poor now a days.
forget all the mechanicals to start with, the body is where the expense is. If you know the engine is broken, look for a good spare,
report back on chassis.
