That's terrible news mate, but out of good comes bad... makes me realise there are good people out there too (Chad - DSTROY) Well done for stepping out and helping someone in need, props to ya mate
Common sense, amazing! Everyone says, yeah, bash the shit out of them, rar rar rar. But in reality, just give them the damned car, I'd rather them take my car, than my life
What condition are your pads in? If you have plenty of meat left on them, I'd say you'd be fine, definately flush the brake fluid though and check the pressures in your tires
Go to Adelaide Radial Tire instead, just on North East Rd near the Holden Hill cop shop. Great blokes down there, Matt's been taking car of my car for a while and does great alignments, cheap too! If I were you I'd be getting a Whiteline front/rear camber correction kit too, should sort out all of your tire wearing issues
