The equation looks like this to me:
This car for the budget racer = never competitive. Not having anyone to compete with in class will get old, very old, very fast. Spending a weekend paddocked next to you I see "competing" as something that's going to be important to you. So what would it take to make this car competitive in ICSCC?
This car looks like something where you'll want to be going faster, sooner and the result will be throwing money, big money, at it to make those gains and in the end, regardless of your talent, it's my opinion that car won't be competitive in ST or SPO without damn near 6 figures thrown at it and I haven't even covered operational costs.
The bigger and faster the car gets the operational cost grows exponentially... Tires, brakes, fuel burn.. everything costs more. I don't know if you're budget minded like myself or you've just won the lottery but regardless of which, I'd look for a different option.
