I say option #3; here is why:
How much track time do you have? Real track time, not cones.
How much rally time do you have?
How much money are you willing to spend on the car?
What is it going to cost to take your car out there?
What are your chances of actually getting in?
Why not do road racing around here at Mid Ohio, Nelson, VIR, Putnam Park, etc?
Think about this:
Cage: $3k
Seat/Harness/Hans: $1500
Race suit, shoes, gloves, helmet: $1500
Truck to pull car out there: $5-10k
Trailer: $1500
Spare tires,brakes,parts: $5k
Fuel:?
Upgraded brakes: $2k
coilovers: $2k
Supercharger with tune? $5?
Sounds like you need a lot of disposable income to do this. I make $50k a year and I can not afford to do Pike's Peak. I wanted to start Spec Miata racing, can't afford it even when a race car can be had for $6k.
I drive a mostly stock MR2 (suspension, tires, brakes, boost contoller) at the track. I figure 2 days at Mid Ohio is $1k (on the high side) when it is done.
$360 to enter
$150 gas
$100 in brake wear ($400 new pads, $120 in rotors)
$100 in tire wear
$50 food
So that is $850, but no hotel. No cage, no suit, no race rubber, no trailer.
