Need for Speed: ProStreet "Nuzlocke" Survival Challenge Episode 1: As You Mean to Go On

So guys, I'm starting a new series, mostly because I'm kinda bored over here.
So, we're starting a Nuzlocke-inspired run, by which I mean the following
I may not use any Total Repair Markers, unless I'm selling a car which I've totalled
I may not re-enter any Race Day after I leave; if I haven't won or dominated it yet, tough.
I must sell one car for any car I total on a Challenge event, as those cars are not my own and cannot be "scrapped" properly.
In these early stages, I'm mostly expecting myself to accrue bank for the later stages. In particular, I'm worried about Nitrocide, since my ability to total cars in the Nitrocide events is... pretty legendary.
