My previous car was a Mk3 Focus RS Track Edition.
Fantastic car, I'd buy it again many times, but my GRY Mk1 is many steps ahead when it comes to pure pleasure of driving.
When I drive the GRY I can immediately sense that it's a unique car, a competition car tamed to get access to public roads, reminding me the behaviour of the Group-N Rally cars I had the pleasure to test in the past.
You drive it with every tool available: the throttle, the brakes, the weight transfer, with a rate of response that gives you the "fitting as a glove" feeling.
The Focus was an excellent road car that was pumped up in a fantastic way, but it's not the same thing. You feel it that you can drive it in a few fantastic ways, but the toolbox is limited by its origins as a standard car.
Very different cars then, and I dare to say that I put the GRY in a much higher league than the Focus RS.
To say it all, I put the GRY in a higher league than the Nissan GT-R R35 I had 10 years ago, but maybe in this case it's just my personal taste for cars.
