Save £12k and get the new Megane. Runs rings round those two, literally.
I find it hard to believe that anyone looking to drop £40k+ into an RS3 will even glance towards a Renault dealership or anything within, no matter how good it it perceived to be.
Someone looking to spend £40k+ on an RS Audi doesn't give a toss how quick or good handling a Megane is.
They will but the RS3 because it's impeccably built and easy to go very quickly in, with little effort....and I doubt too many buy them with trackday performance top of the list either.
