The main reason Nicole has opted for this model in her shortlist of cars is:

A) It needs to do 100miles per day trouble free.

B) Needs reasonable fuel economy.

C) Needs to be an RS with reasonable insurance premium.

D) Needs to be cheap per mile motoring ideally.

That rules a lot of the older Rs's out of the picture unfortunately. If she needs to go fast she just takes the cossie for a good hiding.. so ultimate horsepower potential is not relevant.
