Hi i'm Horstcore i'm from Germany and really like The Crew!
I made myself an chart in OOcalc to review my Bucks and Reputation gainings. Just thought of sharing it with u. :)

Obviously by farming the highest Rep/H mission u'll get the most rep out of ur playtime.

All Driving done with my cheap ass Gamepad on hardcore with manual gear (no drivings help = more fun!).
Depending on how good of a driver u are u can gain alot more Rep/H than me.

The top two Circuit mission are driven with 1299 Alfa Romeo 8C Competizione, pretty awesome Circuit car imo.

All other missions driven with 1299 Nissan Skyline GTR R34

FYI the [REP/H] is just normal calculations plus 20 seconds (thats how long it takes to restart a mission) since u cant just skip the ♥♥♥♥♥♥ intro thingy. I did that so the number would come closely to my true PER HOUR gainings.

The chart is pretty simple and u can do it for urself if u want, here's the formula:

Bucks/H: =E2/(((C2*24*60*60+20)/60/60/24)*24)
Rep/H: =D2/(((C2*24*60*60+20)/60/60/24)*24)
