Top Secret are a little dodgy to me.
My friend bought a non turbo supra in that wierdo blue olour off them and when i saw the car, it had been in a previous front accident(big one) and had been hit on the passenger side door. Yea I know they're cheap but you pay for what you get.
If you want a good, reliable car and great after sales service, go to E&M Unique Motors, in Five Dock.
My cousin bought a R34 GTR Vpec from them. It was immaculate and was a grade 5. They were also the only guys in Sydney that gave their own in-house warranty, every other Dealer/Importer offered some dodgy insurance company warranty, those 3 year warranties.
