I owned the old gen cooper s and had a fair few test drives on the new one.
Heres a few things they dont tell you about the cooper.
1- It will cost you over £20k to get average spec
2- You will have to change all 4 run flat tyres straight away to non runflats -- thats if you want to use the car to its potential without dying.
3- The brakes are not in the same class as the R27
4- The cornering of the R27 is in a different class.
5- The mini is as aerodynamic as a brick - it feels extremely dodgy on motorways over 90mph.
Ive had my r27 for 4 months now and done 3500 miles. I can honestly say I have never enjoyed a car more than this. The whole driving experiance is top notch and the build quality is at least on a par with my mini.
I personally take no interest in all these silly straight line, track comparison tests. At the end of the day its not about how quickly an f1 driver could go in the three cars, its about how quickly and safely I am able to drive them -- The r27 is the easiest hot hatch to drive fast on the market at the moment- you have to give it some serious revs but once your in that power band it flies. They also loosen up a hell of a lot after 2000 miles
Plus the fact that the r27 is 14k, including air con, cruise, speed limiter, cup suspension, recaros, tints ---all of these are extras on the standard cooper s - and the works doesnt come with all the extras I would expect it too.
Most of what you are paying for on the works mini you could do yourself for much cheaper- ie- engine mods, seats, induction, exhaust. You are essentially paying £4k for £1k's worth of engine and body mods just to get a warrante on it-- its a rip off imo
