The new museum officially opened to the public on September 30, just in time for the school holidays.

NAMT manager Phil Costello said it was a relief to finally be settling down at the new site.

"It's good to see that all together," Mr Costello said.

"It's much more user-friendly, no defining paths... one level has made it so much easier to get things in and out and the fact that we can bring the cars in and just push them in into place has been a great bonus."

The new museum comes with all-new cars and motorcycles from across Australia for revheads to enjoy and marvel at.

"One of the pleasing things about this museum is that at the moment we've got vehicles from Queensland, Victoria, South Australia and New South Wales," Mr Costello said.

"That's probably the first time we've ever had cars from so many different states."

A particularly special car according to Mr Costello was a 1986 Giocattalo Group B.

"That's quite a rare car... it's based on an Alpha GTV," he said.

"They were built in Australia, about 15 of them. There are about 14 of them left.

"There are a lot of new cars here that have never been with us before. That was always the intention: to build a museum that was fresh and that wasn't just the old museum in a new building."

Mr Costello said it was great to be a part of the emerging Invermay precinct, which includes the Silo Hotel and Riverbend Park.

"I've been amazed at how many people that park has attracted and as they finish it off and summer comes that'll only mean there'll be more people around," he said.
