If your mate is going to go in the Navy, tell him to wait. My cousin who was 19 at the time went into the army with a bug eye WRX, a month later of owning that he got a 350hp RB26 R32 GTS-4, then got (while with GTS-4) a VK SS Group A (which is his current bunky daily!!), then sold the 32 to get a 5ltr VT Clubbie which he put a twin turbo kit on, and then sold that to get a 500hp atw 32 GTR which is now sold and I have no clue as to what he's getting next. This was all in the space of one year!! You're always out to try and beat your fellow defence force pals.
When I was selling my R I had this co-worker wanting to buy the car for her son. The reason 'to keep my son at home, as he wanted to move out of home and he is mad about Skylines'. Maybe he should try that trick on his dad, but then his ol man might want him out as well hahahaha.
