Thoughts on 2013 Mercedes cls550?

I just compulsively privately sold my 2012 Camaro 2ss the other day so I'm currently car less and in the market. I want to upgrade to something luxurious and fast. I do not like "normal" cars (Honda, Toyota, Lexus, Nissan, etc). I have been looking at Tahoe LTZ's, stingrays, audis, bmw, pretty much everything. I loved my Camaro, was fast and fun but not so much luxurious. I test drove a $45k 36kmile pearl 2013 cls550 today (capital euro cars Tallahassee if you want to see it) and I fell in love with it. I'm 24 years old and my main concern is being stuck upside down with a car payment. I hear that Mercedes and cars similar to Mercedes devalue very fast. I plan on putting 20k cash down on it up front. But out the door I'm looking at 50k dollars. The dealership will not budge a dime on the car as its "certified pre owned". It does have a unlimited mile warranty for ONE year, and a available 2yr extension for 3400.00. Which they wouldn't throw in either. I literally love every bit about the car, the seats, the features, the acceleration is so effortless and it glides over everything. I absolutely love the car. But I don't love buyers remorse. I want to make the right choice and not be stuck with a fast devaluation. I'm also very concerned about the reliability of Mercedes being a European vehicle, I hear they can break down and have many problems? I want reliability ESPCIALLY if I'm spending fifty thousand dollars. What is everyone's opinions on this particular Mercedes model

Too expensive, Get one of these

Hi yes simply this it is a prestige make so carries a prestige price tag when it goes wrong so the extra 3400 dollars is a real bargain should it have issues. As you would be covered should it have issues. In these last few years the Mercedes brand is not up to the same standard it has been for reliability so extra warranty cover is a good idea.

Good Luck on maintaining that expensive beast lol. Wow you just wanna throw money away don't you? Any and every luxury cars are a joke and nothing but expensive holes to work on and repair.

Lexus is expensive cars. Like LFA, RC etc

Nice car. By putting 40% down, you're unlikely to ever be upside down, it that's your primary worry. Worth less than you paid, sure, that happens to all cars. But ever worth less than you owe if putting 40% down? Unlikely. Also remember the fastest rate of depreciation occurred in the first year when it was new 3 years ago. The first owner ate the worst of it.
