I recently purchased a Holden Captiva 5 from this showroom.
I would say that the experience was ok, I would definitely look around with other dealers first.
I was told before signing the contract that the car and the colour was in stock and would be delivered in a matter of 2 weeks. 5 days later, when I called them to follow up, they advised that the colour is not in stock, and gave me 2 options, either to change the colour or bear the cost of delivery which was $700 on top. This wasn't fair as it wasn't part of the delivery was the responsibility of the dealer as part of the contract. If they didnt have it in stock, thye should have advised me before signing the contract. After around 3-4 weeks, they finally delivered the car.
There was no communication what so ever after singing the contract. The customer needs to follow up vigorously, they will not provide any updates at all.
Another important thing is I would definitely stay away from their finance person. I wish I had the recording of what they told me before signing the contract and what they advised me on the delivery date when I questioned the contracts. In the finance contract, they added around $1500 as misc payments which I was told will not be there and they totally didn't agree to their statements.
My advise, please be carefully and read the contract line by line and if possible stay away from their finance people. There are many companies out there who would provide you a better deal. I saved a fortune by getting a finance from a third party instead of Hunter Holden.
