Correct! Explanation:
Some say including this cars cousin would be a problem due to licensing. BUT there's always the chance of doing like the other creators..
The Lancia Delta in GT5 is sponsored by Martini, but the letters are replaced by the well known black boxes. So including the '00 Martini Focus (which is the cousin) might seem difficult to some. However, Codemasters did this for Colin McRae Rally 2.0 by putting the Ford decal where the Martini would normally be.
This car, as well as the evolutions (HINT?) were known for being the toughest of their class. And it was proven right!
Colin McRae at Cyprus managed to roll it several times but the car wouldn't give up. That's proof enough imo.
Bonus: This car was also subject of a very spectacular reunion.
McRae and Carlos Sainz was team mates at Subaru in the mid 90's, and they weren't always that much team players. Take McRae in Spain '95 iirc. He was told to slow down but in turn almost hit a team employee trying to slow him by blocking the road. So when they joined forces again (with the Ford Focus as their weapon) there was quite a bit of speculations, understandably.
This car used to have a different, to some more colorful version. Although it in real life went with something close (yet far) from this car, most other games has the secondary.
The Focus had a blue version in GT2, which most other racing games have been loyal to. The part about sticking to the white one doesn't need an explanation.
Your go again, darn I didn't have enough thinking time to figure out a Burnout-'88-ish riddle for this
