RR3 Wiki:Cars and Available Races

Using information provided on the Wiki I have calculated the numbers

Maximum races are worked out by adding all races the car is eligible for regardless of PR requirements because the race can be won using another car in the series beforehand

Minimum is worked out by adding only showcase & TT from all series car features in

Some series have multiple cars for a Time Trial, Zenith Series is one such where a choice of car is available so it is assumed that another car will complete thus giving a more accurate figure of a minimum, feel free to ask any questions and I'll answer them to the best of my ability

Lexus LFA min' worked out by showcase and trophies required to unlock Ferrari Faceoff
