SL/R231: Ridiculous price differential between the SL450 & SL550
$9K each for the two extra cylinders in the V8 seems rather exorbitant.

What am I missing here?
I'd be happy with the SL450 but I do not care for the wheel options. The SL550's AMG 19" 5-spoke wheels are just about perfect.





450 to 550

I'm just wondering why the V8 engine, which I understand is actually an "older" design, can cost so much more than the newer V6.
And, again, my hangup is the WHEELS. I GOTTA have the SL550 AMG 19" 5-spoke wheels. According to my first meeting with the salesguy, that's a very difficult and expensive thing to do.
BTW, which RED is that? Very nice.




I could easily afford the v8 so price was not a consideration.

Yes it does have a slight orange tinge in bright sunlight but all my other vehicles are red and I can't stand the other boring colors Mercedes offers that look like every other car on the road.

Plus, that's a lot of spokes to clean in between. I've always leaned toward 5-spoke wheels and that SL550 standard wheel is REALLY nice. In fact, I'm amazed that it's standard. Your car is GORGEOUS!gkgeiger: I'll be selling or trading in my '09 Z51 3LT Crimson Red Metallic on an SL. I've had 3 Vettes and this will be the first time I'll be "Vette-less" in a LONG time. Just getting too old to try and squeeze into the LOW cockpit, plus the passenger side on the C7 is a tad tighter than the driver's side. It is one helluva car, though. And, you could load it up with everything and it'd still be less $ than an SL550.
Thanks for your input, gentlemen.

Go back a bit; I think it provides all the pros/cons/opinions on the subject one cares to know.
I too, can not justify the extra cost of a 550 -! I had a SL 400 -in Cardinal Red and loved it - traded it in for a 2018 SL 450 - same color - and even better with the 9 speed and extra Horses !
No need to have a 550 - as the 450 is almost just as quick - and 18 grand is still in my pocket
My reason for trading the 2015 for the 2018, were the 2015 was bought off the dealer floor - the new one looks the same but has Drivers assist, Soft close doors, and the wheel and tire insurance program, which I did not buy on the 2015 - I could not add it after the purchase was done, so when I ordered the 2018, I had it included.

Make offer - My Mercedes Dealership tells me they retail for 2,926 for the set - (fronts are 538 each, rears are 925 each) They only have 28 miles on them as they were taken off
my 2018 Mercedes (pictured on the web site with the wheels of my choice) they just want to find a home - selling all 4, will not sell individually - MAKE OFFER - Pick up

I like the ones you chose, BTW. Your car looks FABULOUS!

I suppose it's a question of taste. I always disliked the SL550 wheels and took them off in a matter of days and used them for snows.
They are not available for the SL550 for a reason; it is to differentiate the models. This shouldn't be a surprise though as each model is catered to a slightly different market.
As to the price difference; I wouldn't call it ridiculous at all. We had hydro-locked a few months old SL550 and the replacement engine with labor clocked in at over $70k. That was in 2013 though...
If you like the wheels so much, takeoffs are the way to go: https://www.ebay.com/itm/19-Mercedes...JaDIik&vxp=mtr

You are correct; the differences have been discussed previously. I had scanned the posts before, but I was looking to zero in on the PRICE difference which just seems like GOUGING to me. I still don't see how there can be $18K worth of difference between these two engines.

I was looking at a AMG GTC convertible last week which electronically is at the same level of the SL. That car was $185k...
The grand tourers will get squeezed between the more technical, less roadster-like cabs (like the E or S-Class cab) or the high-performance roadsters. I don't think money makes a big difference. At any time n the history of the SL it was a more expensive car than other MB sedans or competitors and sold just fine. But manufacturers now cater to micro-niches and literally have 50-100 different models/configs. MB itself has 6 different convertible models, not counting engine variations...

Between the SL and other Mercedes is just its ranking in the Mercedes hierarchy due to price.




The C, E, S Class cabrios are not roadsters; they are topless 4 seat derivatives of their coupe brethren's .
The AMG roadsters are more sports cars than GT's (even though its in the name; they definitely misses the creature comforts of the SL)
