EL03RZO

Need a little help here I know it's difficult to tell from photos but I've just sent my 04 Z into a lot of cal nissan specialist for a health check before heading off on a euro road trip finishing at the ring that I've been planning for months. The guy seems very good at his job and thinks the car might be really far gone with rust and needing body panels welded in. Parts from Japan (not overnight) 6 weeks delivery meaning I've no chance of making the trip. Does anyone know of a UK body panel shop or if this is a common issue? Seems a bit extreme. haven't been under it in a bit and am away at work at the moment so can't go stabbing it myself for a week or so.
