I got my car from a guy who purchased his car off HeartBeat cars. Whilst I don't have any personal experience with them directly, the car speaks for itself and its immaculate, clean, straight rails, no rust etc etc.
I've been keeping a keen eye on prices and whilst good examples are pricey...at the end of the day you usually pay for what you get.
A R32 Vspec II with 50k kms on the clock for $30k AUD landed...is well quite frankly almost too good to be true.
