I've just had my cars reset at the end of the MJL league season. All attributes appear to have been set to 63 with the exception of brake (75) and cooling (46), I assume this is because my CD has strength in braking and weakness in cooling. So far no problem other than a weakness seems to reduce the attribute by 17 points whereas a strength only increases by 12,
All three of my suppliers give an increase of 1 in acceleration so you'd expect to see this attribute 3 points higher than the rest but instead it is Fuel Economy that is three points higher (66 against 63 for the rest).
