I would never do a full package like this. The great thing about having such a fun car with so many upgrades available is that you can make yours totally unique to you, or build it slowly over time, adding parts, seeing how they work, then adding more. You can mix and match, you can do totally cosmetic upgrades, you can tinker.
Just read Rob's thread about all that he has done to Punisher. He's poured far, far more into that car than he paid for it, and he's still not done, I'd wager. Modifying a kappa and making it your own is the best part. You'll never "be there."
It's easy to forget that its not about the destination, its about the journey. That's why we love cars.
