I do wonder what mine would be worth if i put it up for sale (not that im planning on selling as i love driving it). 45k and im the 2nd owner. I think it would be a hard sell due to the mods/non originality.
Bilstein b14. Mine runs them, compliant for road use. Previous owner fitted them when the sachs needed rebuild, and said they were as good, if not better than the sachs.
Avoid the bc's.
If money not an issue, go Ast/Nitron/Ohlins. I have Ast5100 on another car of mine, and the damping is...
The tyres take the paint up off the floor if parked in the same spot for a period. Im not arsed about the paint coming off the floor but it takes a while to wear off the tread. Decent paint and prepped well too cant win.
Great job on the repairs. I think the general rule with these clios is if any visible rust around rear arches or above sideskirt, then its going to need a bit of surgery.
Just change the manifold to cat joint to a vband clamp and short bit of flexi hose. Any decent custom exhaust place will be able to do it if you cant weld it yourself.
Ive not used any bodyshops round here in years so cant recommend any, however id try and get the dents removed by PDR before paint. Just Dents in Darlington are spot on, i had a couple removed from mine recently.
