You'd be suprised at the amount of modern cars that are in concours in varying classes, wether that be Working class, original or modified. The hard one to do is pure concours, everything, and I mean everything, has to be exact. I know from doing my Ford Granada, every rusty bolt, washer etc has to be replaced with the original item some of which are very hard to find. Everything from stickers down to the colour of the coolant will be judged.
Tyres are even judged on whether they are are the correct fittment, make and tread pattern, extra points are awarded if they still have the wee rubber nobbly bits, I know I've got them, fitted to a set of brand new wheels bought from Ford.
Concours is very very hard to correctly and requires deep pockets and patience, so far the Granada has been off the road for 2 years being prepaired. Only problem with having one is once it's done, all that effort to take it out in the rain...... I think not....and if it's caught in the rain that means a major clean of the floor pans especially if you remove the underseal and suspension components, not to mention the weekly saga of maintenance to ensure that all those new metal suspension parts don't go rusty by spaying on some wd40 and wiping everything down as it wouldn't look good when the mirrors are positioned under the car at shows if it were rusty.
There are of course some who's concours cars never even go on the road, they are known as "trailer queens" for obvious reasons. It's good you have the original BOS, and manuals, tax discs from day one are good to have as well along with brochures, original dealer plates and stickers. Some people even have the display signs from the shoowroom to go with the car.
All in all, good luck with the concours project and look forward to seeing some piccys cause I ain't doing another one(Y)
