I think your better scouting out a really good private vehicle.
Both the Canberra Import dealers mentioned mark up the cars something shocking.
Also, i've had friends speak bad of them, and that warranty is worth almost nothing.
Something went wrong with his car, Turbo i think, and they told him they won't cover it because he didn't use premium fuel. Even though he did...i dunno, i'd steer well clear of dealers.
I looked around, knew what i was after and how much to pay roughly, and found a really nice example in Sydney. Drove up, took a look, came back, got my cash together, went back the next weekend and bought it.
I see where your parents are coming from, with the Warranty though. Mine are the same.
Prestige are great, i've heard so many good stories come from customers of theirs, and i've talked to Geoff a few times, and he was nothing but helpful.
Oh yeah, and Go Canberra! Best place to own a car! Great roads, no traffic, and little theft
