It will kill the car if it's not serviced properly.
If you are often driving the car hard, you need to keep on top of oil level, oil changes, brake pads etc. probably more often than the manufacturers recommendations.
I'd go with the other people in this thread though, racing on the road is a bad idea.
Also, racing on a dual carriageway in this you will lose, even a decent mapped diesel will destroy a 197 in a straight line.
Get it on a twisty circuit and they'll soon be specs in the mirror.
