Ah another 130 saloon same colour as mine, i just love red 130 saloons. Genuine GM panels are on ebay, there was a genuine rear quarter for a saloon on there a few weeks ago for £130 was on for a while. There are other GM panels on there now at a price!!!. Mine is original apart from a rear quarter fitted in 1994 after white van man creased it (i paid betterment as i did not want the panel repaired just replaced) I am sure there are people on here who can advise for both genuine and pattern parts as there are a few excellent projects going on.
I'm not sure you could call mine i200 as it is not a Swiss car. The car has been sold new in Sweden instead.
Good news, I've found better doors for the left side. From my hometown, cost me nearly nothing. Happy about those.
