Buying new

There are plenty of reasons not to buy this car. It's very expensive, costly to maintain, liable to depreciate heavily and considerably flawed when compared to alternative options like the Porsche Cayenne.

Ultimately, however, if you're even considering a G63 then that probably means that you want one and are well aware of the pitfalls.

By no means is it a terrible car, in fact it's an endearing and entertaining choice, but those seeking comfort would be better opting for a Range Rover; those looking for true off-road ability a standard G-Class or even a Toyota Land Cruiser. Drivers looking for performance would be best opting for the aforementioned Porsche.

When it comes to specifying your car remember not to go too overboard on the options list, escalating the substantial list price even higher, and consider opting for lighter interior colour schemes. Dark colours, with garish wood trim, can appear very dated and leave the cabin feeling very gloomy and oppressive.

If the G63 AMG is too aggressive then you could opt for the standard G350 diesel. It's considerably more economical yet still very capable.

Buying used

It’s very difficult to justify buying a used Mercedes-Benz G-Class G63 AMG. Firstly, Mercedes-Benz offers the M-Class ML63 AMG. It’s a modern car that’s refined and more competent on the road. It’s also considerably cheaper than the G63.

There are other alternatives as well, like the Porsche Cayenne, which are far better to drive and considerably less costly. The G63's residual values are similar to its rivals but given its higher initial price and niche appeal a used example will still command quite a premium.

A lot of buyers will be letting their heart rule over their head, however, so if you intend to buy a Mercedes-Benz G-Class G63 AMG then try and find an example that's been cosseted and cared for. A full Mercedes-Benz service history is essential.

Do ensure that even minor faults are rectified before you buy the car, as even a simple issue may prove costly and difficult to rectify. The G63 is a very complex car and labour costs, rather than parts, may be your worst enemy.

If the particular car you are looking is older and has been serviced by a specialist independent garage then don't be overly concerned, provided the garage in question has a good reputation and the tools and knowledge to work on the car.

Selling

Few people will be in the market for a Mercedes-Benz G63 AMG, so you could be waiting some time to find a buyer for your G-Class.

G63 AMG residual values are acceptable but given the car’s high value you’ll still lose a significant amount of money when you choose to sell it.

To help find a buyer more quickly, place the advert for your G63 in specialist premium car and four-wheel drive magazines. It’s more likely you’ll reach the right person this way.

You may also find that certain prestige or performance dealers may be able to sell the car on your behalf, for a small premium.

Those interested in your car will be looking for a comprehensive Mercedes-Benz service history. Most will want to buy a G63 that has been extremely well cared for. Any damage or issues are likely to put off many prospective buyers.

When advertising a G63 there are a few things to remember to point out. It’s worth mentioning Mercedes-Benz’s widespread dealer network, as well as the G-Class’ durability, history and capabilities.
