$2.8m supercar safe in its own bunker

New Zealand's hottest set of wheels made it through this week's quake without a scratch, thanks to the "bomb-proof" bunker its millionaire Christchurch owner parks it in.

Mainfreight co-founder Neil Graham, who recently took delivery of the most expensive car ordered by a Kiwi buyer, said he didn't spare a thought for his $2.8 million Aston Marton supercar when Monday's 6.3-magnitude quake hit.

The sleek One-77 is inside a garage strengthened with reinforced concrete, which Mr Graham joked could withstand a bomb blast.

"We haven't had any problems with it, touch wood. It's just like a fortress. We call it the bunker - it's got a big sign on it like a large number plate that says 'Grumpy's Garage'," said Mr Graham, whose nickname is Grumpy.

"No, I didn't even think about the car. Mind you, if you've been in continuing earthquakes like we have, then you can only think about your current situation and your wellbeing. [The car] is in the best place that it can be in Canterbury ... and I never gave it a thought, really."

But Mr Graham admitted the constant shakes had prompted him to consider what he would do about his black beauty if a violent quake threatened to topple the bunker.

"If it was a terrible rumble and was really falling over, then I'd undo the safety locks, which would take a couple of minutes, and I'd have it out in the clear."

Mr Graham is building a quake-proof three-bay garage for some of the other luxury machines the passionate car buff keeps around his palatial Hoon Hay Valley home.

Asked if he would eventually move the One-77 there too, he said: "No, that'll stay locked in its fortress. It's a beauty, and I wouldn't put it in any ordinary garage, that's for sure."
