Have had one for the past 3 and a bit years now! Even though mine is abit of a project and garage queen that hardly gets driven i still love it to bits! I love the boxeness of them! Designed from leggo block i personally believe, even pretty much everyone i work with dislikes it i don't care!
Skylines were ahead in there young days! Even now you may have to spend extra on it to get it going like your VZ Falcon etc but it's your own personal preference. If you think your car is out dated and you reckon a commo or falcon will meet your needs go for it, i would never buy or own anything that isn't Nissan or Mazda but that is just me.
