I hear ya have to get to LVL 25 b4 enduro's show for BOB to race??
I got the Sig Ed and its a real grind to get the driver to LVL up... Having said that though I have 5 drivers on the go, two of them are at LVL 18 ATM.
The Sarthe race takes around 13 minutes and gets ya a heap of $ and 8 to 12k of EXP depending on how ya manage BOB.
I been sticking BOB in my Chrome and Stealth cars to run in series, makes it easy for him
Thx for the link to races and prize/xp
