What to check when buying a 2007 GL450
A friend of the family has offered me a 2007 GL450 with 71k miles for around 3k under market price. He’s bringing it for me to look at tomorrow night, and I’m planning on buying it, assuming there are no major issues.
It’s got a clean title, he’s owned it for several years, and it seems to have had all the regular maintenance performed. 2 air shocks have recently been replaced, so I’m assuming another 2 will be due sometime soon.
I’m no stranger to owning older luxury cars - I’ve had a Range Rover, an Audi and 3 Jaguars, so I’m aware that this won’t be like owning a Civic or something. However, I don’t want to buy something that’s a complete money pit. I have the advantage that I live in México, so labour is very cheap here, and I’m relatively capable at fixing basics on cars - I’ve changed air shocks, throttle bodies etc on my previous cars.
My main question is this: is there anything in particular that I should check before buying? Any specific issues that are really common on these? I’ve already read some of the topics on here, but if anyone has anything to add, I’d be very grateful.
Thanks
the rest is to check that it has had preventive maintenance.

I suppose if you want to use the ecu that controls the 5.5 liter motor you’d have to marry that to your car via das/star and that’s where you may run into compatibility issues.

That's how a number of different engine swaps are done. A reflash is usually easier than trying to adapt a complete ECU from another car.
I wanted a beater but not something with potentially major engine problems.Thank the universe I found this here on MBworld. On a bright note two days ago I saw a BEAUTIFUL 550 super loaded and told the owner I would be interested if they had the intention to sell. I still think that is the way to go 2010+ so the trans is less likely to have the conductor plate or engine issues but have taken the major amount of depreciation. I really like how MB has made this vehicle tough mechanically and rather easy to work on. Coming from a TT V12 coupe car that is
Let us all know if you get one. How is Mexico? Have you heard of Peter Zeihan? I think the US and Mexico will have superb trading relations moving throng the next few decades.

Never heard of Peter Zeihan, but I just googled him and read a few articles, and I agree with most of what he says. I love living here, and most of my work here comes from US companies, so improving relations are always an advantage for me. I accept that my quality of life here is probably not representative of the general population though.
I've always wanted to visit Puerto Rico - my wife is less keen as she thinks it would feel fairly similar to Mexico, but I'm not so sure. I was watching an old Anthony Bourdain episode when he visited, and it looks like a fantastic place, albeit with some of the problems we have here. Nowhere is perfect I guess!








What's the over/under until the next failure?
