buyers are spoiled for choice when it comes to choosing where to buy a Mercedes-Benz from - or so it would seem.Mercedes-Benz ownership is something many of my local Sydney residents desire for years prior to obtaining.In fact it's right up there with the dream of owning a Rolex watch, a luxury boat and a luxury home.So when you get to the stage where you are ready to buy your Mercedes-Benz, you want to make sure you buy well.Does having more Dealers to choose from mean a better deal?More choice means more competition, which is good for Mercedes-Benz buyers. Since most buyers in Sydney fully understand economic forces, it goes without saying that Mercedes-Benz Dealers are keen to win your business.Are all Sydney Mercedes-Benz dealers the same?Absolutely not.Each one is different in certain ways - and I don't mean just in location.When looking to buy a car, and especially a Mercedes-Benz, elements such as service, price and availability will factor into in your Benz dealings. Most dealers will have a good level of service and availability.Essential questions you must ask to avoid paying too much - or even worse buying the wrong car:These are a few of the vital questions you really need to ask yourself before you venture into the car showroom.Questions like: Which Mercedes-Benz model will suit my needs more? A-Class, the small Benz hatch? perhaps an M-Class for the large 4wd size Mercedes-Benz, or are you more suited to a CLK-Class coupe? The more you understand your car needs the more you will be able be clear about what the right car for you is.Why is it so essential for you to know in advance what the right car is?You need to be in control of the Mercedes-Benz purchase, not the salesperson. If you do your research first (the internet is a great place to start) then you will be able to make a better decision.Some dealership staff will try and promote certain Benz models that are in stock because those vehicles are almost certainly costing interest as they sit there. Be firm with what you want before you accept the first car suggested!How do you know if you are being sold, or if you are doing the buying?Look for a salesperson who asks questions. If you are being "told" what to buy rather than "asked" then you are dealing with a pushy sales person. A salesperson who sincerely seeks your exact requirements is probably serving your needs well.Do not buy until you are comfortable to make a commitment and be prepared to stand by your decision.If you are uncertain or in doubt, don't be in a hurry to make a decision. A rushed purchase will often lead to buyer's remorse and you may regret your decision to buy a Mercedes-Benz every time you step into it.
