I Have been doing MOTs on cars for 10 years now, 3 years on Renault, must say that renos are usually pretty good when it comes to mot time, common things I find are
Brake hoses split, Siezed brake valves, defective brakes(badly pitted discs, rear brakes leaking fluid), broken road springs, blown shocks, ball joints, anti-roll bar bushes, split CV boots and rack boots.
Very rarely get a rusty one in.
Most of the items above are easy to fix.
The list sounds a lot but when you compare it to some other makes it aint to bad.
