Purchase advice
really hoping for some expert advice since this is my biggest purchase (I’m 24)
I’m super excited about these two vehicles I’ve been looking to purchase, only problem is I can only buy one.
2015 S63 AMG vs 2015 S 550
S63: 93,000 Miles, tuned to push 750hp, good maintenance and service history
S550: 38,000 miles, 1 owner, excellent condition
just wanna know the scopes of how much I’d expect to spend with the S63, it’s only $3k more but the mileage and tuning on it, I’m expecting a fair amount of spending in the next 25k miles.
so please advise me on what you think I should get, of course the monster is so tempting but I’m also not trying to spend all my money on a car.
Thank you !!!

Of the 2, the s550 is the safest but it's a high priced benz $100k+ OUT of warranty. You should be prepared to lose your a$$ on this type of car without an extended warranty and I bet you don't wrench your own engines.
what amount of cash in the next 2-3 years would be a deal breaker in terms of cash spent on maintenance and repair of either car?
the s63 is laughable in terms of what you should expect -- a tuned m157 with 93,000 miles ... yikes ... turbo lines ... $8k, engine harness, $2k, brake job $2-4k, trans $4-7k, suspension, control arms, tie rods... $500-1000...
this doesn't include routine maintenance.
You'll need a really good mechanic to privately inspect both vehicles, scope cylinders, leak down tests, check all sensors for leaking oil etc...
Good luck
I have, in the UK, a 2015 S500 which is the similar spec as you were looking at. It hits 60mph in 4.7 second and plenty fast enough.
Yes the S63 sounds amazing, a friend has a coupe version, however if he ever were to need a front brake job it would be horrendous in cost..
my S500 had 39000 miles on it 3 1/2 years ago when I got it, it is very well specified and even has the rare MBC as well. It now has just over 60000 miles and a wonderful car, I have managed to keep the miles down as I have other cars and keep the Merc as "best".
The S63 is the better car, no doubt, but I’d be very wear of one with near 100k miles. Unless you have very deep pockets.




So I did not own any extended warranty and my 16 Maybach did have a few more repairs than I would expect out of a car with less than 75k miles. BUT the world did not end when I had them fixed!

Something to consider as well is an extended warranty. Fidelity and Freedom Warranty are accepted at all Mercedes-Benz dealers and licensed independents in the country. You can get "CPO ELW" coverage on the S63... but the information below is going to be for the top level "bumper to bumper coverage only available on the S550 because of the milage.

Here is a pic a couple months after I bought my S550, it was a funny comparison in size compared to my mom's "sporty" Fiat 124 Spider.

My thoughts - I just purchased my second S63 AMG , a 2014, with 44k miles. It took a new set of PS4s tires, a turbo oil line repair and fluid change throughout (about $5200) -all workat a mercedes indie. I now have a dream car that I believe in. Great ride and aggressive when I want it.
IT TOOK ME 9 MONTHS OF PATIENCE TO FIND IT -- It had to be right color, fit my budget, local enough that I could go see it, miles below 50k , and equipped like I wanted it.
You will find the website "mbdecoder" to be a great help. Free and gives you a full build list. I found myself knowing about a car than many sellers
Good luck. Enjoy whatever you end up with
