Many thx for this very helpful indeed.
Thanks in Advance
- in 2017, the SL added Apple Car Play / Android
- In 2017, SL 450/550 added the new MB 9-speed automatic transmission
- In 2017, ABC (perhaps one of the most talked about and potentially polarizing discussions points throughout the forum) became an even more expensive and even more rare option, and included a new “curve” feature.
Sure there are other changes both of a cosmetic and technical standpoint - but having cross shopped a lot of SLs, I found these options to be the most likely to influence decisions.
Good luck with the search!

As for build numbers, my anecdotal experience was that I noted more available 2013-2016 SLs on the market with ABC than I saw 2017+ with ABC (still very few). But perhaps that is more a function of the non ABC cars being immediately more available on lease returns from 2017 up.
I still feel Apple car play and the 9 speed are the most significant changes, beyond the cosmetic and mild technical changes. The newer turbo six also sounds better to my ear now than the prior exhaust! But that is all just opinion and conjecture!


Here we are approaching the end of CY 2020, and M-B still has the SL listed on its website, complete with the configurator. What's up with that? They quit building these things months ago. Do they just not maintain the site, or what?

This will probably raise some eyebrows here too.... But we drove the 550 and the 450 both models quite a bit and drove quite a few in Florida when we wintered down there and shopped. I don't know why, but we actually liked the 450 better. The interior is exactly the same. I think the engine is actually the only difference but I could be wrong.... But if I found a 450 I liked, I would highly recommend looking at it. We are very happy with our 450 and it is plenty responsive, plenty fast, and plenty quick off the line. I know Corvettes and Jeeps.....SLs - not as much, to be truthful. But just drive some 450s before you cross it off the list. I am probably just imagining it, but seat of the pants feeling of the 450 and its nimbleness we liked.

We just liked the front end a little better with the curves and headlights that looked better to us.
Probably a big reason we decided to only look at 2017 and newer was the brilliant blue color. My wife saw a new one on the showroom floor with white interior and it absolutely floored her. I never saw her have a reaction like that to a car. It was a hard job to get her to leave without buying it. From that day on, we patiently looked and drove and shopped them, but I pretty much knew that a blue and white SL was in our future.....
One point I was trying to make earlier to the original poster was to not JUST look at the 550.... Look at the 400 and 450 as well....just test drive both. We had a few instances in Florida to test drive a 550 against a 400 or 450 back to back... We bought the 450. The 550 was a good drive, but we really liked the 450 a lot.
I also strongly agree that the SL450 is a much nicer driving car than the 550. Before ordering my 2019, I drove both models back to back, several times, on different occasions, because I could not believe that I liked the V6 model so much more than the V8. The lighter weight over the front wheels is very noticeable and really sort of intoxicating. It gives the car a nimbleness that I found lacking in the V8 model. The fact that virtually everything is exactly the same between the SL450 and the 550, except the engine, and there is a $20,000.00 price difference, is absolutely amazing to me. That said, I found the driving dynamics to be so much better in the 450, that I would not have chosen the V8, even if there had been no price difference at all.
That is the EXACT thing we noticed as well but I did not do as good of a job as you describing the feeling. I never knew why, but I always suspected the weight or the POSITION of the weight from the 450 to the 550.
I have owned a couple of fast boats. Just moving the weight around in the boat from one place to another would make a huge difference. At first, I thought it was maybe tires or tire pressure, but it was a difference we noticed every time. I finally thought it must be the weight and the location. Maybe it has something to do with balance. The original poster stated he was looking at moving to a 550 and my reply was meant to just recommend driving both models before deciding.
