The car was parked on the corner of Queen St and Young St in New Plymouth, down the road from where he's working on the construction of the new Len Lye Centre art gallery.
"I thought it was just a big joke because all the boys from Len Lye went down to view it as well, and a couple of people had to move their vehicle, and I thought they were joking, so I sort of walked out with a smile on my face," he said.
"And then when I seen a tree sitting on top of my car .... I just didn't even want to go see it. I stood up there for a while. I don't want to see my car looking like that."
He was eventually persuaded to approach his crushed car by a police officer.
"It was speechless, shocked. I couldn't believe it," he said.
"It was my car, it could have hit someone else's eh? It had to get the car in the middle."
It was "an upside" that no-one was in the car at the time, he said, because it was "pretty munted".
"I wouldn't [think] that it would be fixable," he said.
"Looking at it, there's a lot of work to fix, there's a lot of damage. The front guard's dented, the bonnet's dented, the windscreen is smashed, same as the back windscreen. The roof's all caved in. It's dusted.
"I'd declare it a right-off because all the structural, all the pillars are dented and everything.
"I don't really want to drive it again. I get a bad feeling after it's been crashed or broken, you know."
The car was a "dream car" for Mr Corrigan, who had "always wanted to own" one.
"I didn't even get to own it for that long."
He added: "It was the first expensive car, the first nice car I've bought for myself ... You drive it nice and look what happens."
The car was insured, but Mr Corrigan had to wait to hear back from the insurance company before knowing what to do next.
In the meantime, he had yet to sort out a new ride.
"I've got a scooter in the shed, I might have to use that."
