You're joking yeah? You're not actually considering that as an actual option are you?
Don't mean to offend you, but it's a 33 GTS-T, it's not something rare. Why the f**k would you even consider having ~$10k sitting there for a few years to one day, maybe, turn it into a track car when you come back...
But I'm sure you were just joking, because any half wit would understand that parking $10k in a garage for 3 years to maybe turn it into a track car is the most ludicrous thought one could have. That same half wit would know that $10k in your bank account when heading overseas is far more beneficial than a $10k garage ornament that will be worth $3k when you get back to turn it into a track car, losing ~$7k worth of potential track mods in the process.
Tough decision though..
