Thoughts on 2013 E550
And will I be disappointed going from E55 to E550? I like that it's more modern, but I like the hit if my E55.
Now, the E550 is of course a newer car with less miles, so it probably has some technology upgrades which you may or may not care about. The good thing is that I think you can add CarPlay or Android Auto fairly easily. Here is a good discussion about adding the RoadTop module. https://mbworld.org/forums/sl-class-...y-install.html
You may want to watch this video first. What is not covered is the reliability of the newer engines and problem with cylinder scoring. Still, an interesting video.

My car has crank and sc pullies. Exhaust and other mods. It's very similar to his black e55 in the video. Almost as clean. It's the allure of a newer car is all. I feel like if I don't sell now, I'll probably end up owning it another 10 years.

Made it through that around 110k miles and thought ‘Shewee, glad that’s behind me’ and then turbo crapped out around 130k miles. Still own it and gf drives it with CEL for low boost (and it IS the turbo that failed), mostly because I have a decent investment in it and will not pass that problem off to some unknowing young/eager buyer. If the turbo hadn’t failed, I was going to sell it for ~$10k when I bought the E63S.
I bought my ‘14 from a MB dealer out of state for $23k with 56k miles and felt it was a good deal. Frankly, I still do…just wish I knew more about chain noise issue, acted faster, etc. My car is hella quick b/c of the OETuner Stage1 I put on it…but likely also contributed a bit to the turbo failure.
Just my $0.02
Beautiful car, by the way. And 103,000 miles in 20 years ain't a lot -- 5000 miles per year. Personally, I'd keep it.
I got rid of my 2004 SL500 because the ABC was starting to have problems, the gas tank baffle had come loose and would bang around, and I always worried about the hydraulics of the top. I traded it for my 2015 SL400 since the R231 had fixed a lot of the issues with the R230, was more powerful and faster, had significantly upgraded technology, and was 11 years newer. Still, I think the R230 still has an ageless beauty.
You should prioritize what you want most out of a car and compare the two. Heed what Jaybird said about the engine.

But this turbo thing is rough…still struggling on whether to actually spend $7-10k more on a 10yo car w/135k mi. What if the tranny goes after the turbo job?!
Mercedes has addressed this by using a one-way check valve with updated tensioners to reduce or eliminate the drain-down of oil. The fix can be retrofitted to older engines, but many times the damage of excess wear has already occurred.

"The secondary chain tensioners produce a rattling noise until the engine oil pressure has built up. No consequential
damage is to be expected. Other causes not related to secondary chain tensioners are also possible and not described in this LI.."
Though it states no consequential damage is to be expected, clearly there has been. The attached document is version 14 (12-11-2019); there may be newer versions. Original (version 1) was published 07-16-2013. So, you can see it is continually updated. I don't have direct access to TIPS.

I would not want to spend the money at this stage on the turbos. As you stated, what will be next. There comes a time to cut and run and all too often it's only obvious after the fact.
chain issue as noted
bore scoring
oil in harness
drinking problem

Knowing what I know know after owning the car and getting things fixed proactively, I wouldn't buy anything M278 without exceptional maintenance and a thorough inspection, including even a borescope of the cylinders (and a warranty just in case?). Best of luck and don't trade your known hotrod for an unknown potential problem semi-hotrod...
Not sure this is the video I remember seeing, but it came up in my search. The 722.6 seems to be a much easier transmission to maintain and repair.
