Dear Erich,
Just wanted to let you know that we have paid a deposit on the car and the deal is done. I am very happy with the deal and happy that we will have a car waiting for us when we get back to Australia.
Thank you so much for your help, it really was great peace of mind knowing that someone who knows what they are looking at is helping you. We'll be very happy to recommend your service to all our friends overseas, I think they will find it extremely useful and good value for money. My husband is a diplomat and so we have to buy and sell cars every few years. I know that we will call you next time we come back from a posting and need to buy a car again.
Can I make a suggestion? You should try and advertise in Australian Embassies, High Commissions and Consulates. Maybe even other nationalities coming to Australia who are not familiar with car purchase arrangements. I think you would get some good business from a lot of people who don't have the time or expertise to make confident buying decisions.
Anyway, best of luck for the future, as I said I know we'll be in touch again when we next need to buy remotely!
