I have a couple of these (-a turbo & gtx) - marvellous cars. I've a shed full of spares too -if you get stuck. (Panels,glass, mechanicals etc) Structurally - its a Renault 18 (keeps the cost of consumables down).
'Mr Reno' (on autoshite) is a Renault mechanic with hoards more fstuff & seemingly limitless knowledge.
Good luck-enjoy!
