Just had a chance to watch the Harris video gilford is referring to:
"If you're in a C63 or M3 on any kind of B road in the UK, don't even attempt to stay with an A45, because you will fall off"

- now that is a very funny and smart line in a film like this.
I really have to ask why he thinks an RS3 wouldn't do exactly the same, if not be a little further down the road from the AMG, it makes no sense. I know this, me in an RS3 v me in a C63 and I wouldn't know which way the RS3 went.
Oddly all the things he likes about the A45 apply equally to the RS3:
"It feels like an Evo or STi (but with up market branding)" - that's exactly what an RS3 feels like, I often call mine my Impreza for grown ups.
"It's hard riding rather than stiff" - again same would apply, the RS3 is a hard ride but not the back breaking ride of say a Megane 265 Cup.
"You get in this car and think this is fast, the way it covers the ground is astonishing" - all descriptions I and many passengers have applied to the RS3. I've seen no figures that suggest the AMG is faster than the RS3.
"It makes a great sound on the upshift" - getting boring now I know, we've had this feature for 2 years and 5 cylinders sound much better than 4.
As for the BMW apparently it's better because it can "do little squiggles out of corners"

I have never seen any BMW perform such a thing on the road and I drive on some quite deserted roads, but if all the BMW's near where you live do, let me know. In the midst of him BuMWfest eulogy he does admit the BMW isn't great on bumpy roads and that if you want to be fast and safe in the winter you should choose the AMG (or indeed an RS3...!)
Anyway enough of that to the track, the ****** BMW was cheating again - Michelin Pilot Super Sports on the BMW vs Michelin Pilot Sport 3's on the AMG - and the AMG was still faster.
And on that note I reserve my final

and

for Mr Harris because in my R26.R with just 230bhp on Toyo R888s, I beat both those times by half a second, which is a good gain on such a tiny track. Oh and here is the video evidence to prove it too.
As for the RS3 on Michelin Pilot Super Sports - I have lapped Llandow in under 46 seconds but as some of you know my Go Pro was broken so for a couple of weeks you'll have to take my word for that. So I'll suggest an amendment to his claims - he didn't take an RS3 because it would have slaughtered them like in his previous video vs the M135i where he had to admit for all he hated about the RS3 it was over 1.1s faster than the M135i when lap times were revealed - and the RS3 was on the standard Conti's.
So now we know I'm faster than Harris does that make my view more valid than his!
