Quick calculation, since 5.0.0 the averages are:
 * 670 - to win all the cars / maintain a full garage
 * 1013 - to complete all new series / 100% completion

This assumes you complete all series and special events (i.e. it's net) but it doesn't include farming, daily bonus, WTTT rewards etc. So whilst it is hard, FM do appear to have listened and it isn't as bad as it has been.
