AMG GLC 43 versus 63
If you want to tune please consider a used one.
Our GLC 63s will be about AUD$180 - $195k, or approximately USD$121- 131k.
Absolutely massive cost difference for us, and that's why I've got the 43 on order. You guys are really lucky with your pricing even after accounting for currency differences!

Bad advice my friend. This topic has been covered ad nauseam - MBUSA is very clear that any alterations that cause damage may have warranty denied. Hell they can deny warranty if you race your car much less tune it. Everyone knows someone that has a tune and had their chair fixed under warranty, but you kill any part on your motor or transmission and have fun fighting that one. Renntech on their own website tap dances around this issue which should be a red flag. And sure there are dealers that will install a tune for you, but your dealer doesn’t back the warranty.
The general consensus amongst countless hundreds of posts on not just this forum but others is to modify your car only if you’re willing to risk your warranty. But if you can get MBUSA to sign off on a tune please send us the letter, that would be the Holy Grail for many.
The AMG GLC 43 was $70,570 (US Dollars)
The AMG GLC 63 was $81,340
Or a difference of $10,770
I did the night package, upgraded sound system, digital display, etc for the 43. So its roughly $10k more for the 63 ....
Kids are young and should fit fine, my wife is getting a GLS soon ..... That will be our primary family car. I can tell that the debate here is similar to debates I've seen on bimmerpost. I know that the 43 is more than enough car for me and what I will use it for, but honestly the regular GLC is probably more that enough car realistically for what I will use it for but I love the idea of the twin turbo V8. There aren't too many cars like that left anymore and in 10 years they will be extinct ... decisions decisions ....

before you order check mbusa cpo's got glc63's...... might get lucky and find the 63 for the same or less than the 43 with all your options...Ya never know.... I traded my 16 gle63s coupe for basically a leftover 2018 gle63s for stupid cheap money in late 2019.

2018 in Coral Gables with 7k miles for $64k. That’s a damn steal.

Further, if my kids were still young and it had to be GLC, I would go with 43 over 63.
But my most honest advice, considering three young kids, is GLE63/63S new (at least 15-17% off for leftover '19s at most dealers) if budget allows or if not, then certified '16 or '17 GLE63(S) which would be about the same price as new GLC43 or a certified '18 GLE63(S) which would be about the same price as new GLC63. Yes I understand OP's spouse is getting GLS, but I still would go with a low milage certified GLE63 over new GLC43.
Last data point on Renntech. So I emailed a RT MB dealer and asked if they would put in writing that the tune would not void the warranty. They refused to do so, but offered "we’ve done 50 of these without any issues". I personally would not put my MB at risk based on some anecdotal evidence, if even true.

Something to think about when your kids are older. My 17 year old loves driving the 43 when she can…if it was a 63, I don’t think I’d be so comfortable with it lol

I have a GLC 63 and have driven a Renntech tuned 43. The tuned 43 was impressive but my stock (no longer stock) 63 pulled noticeably harder. Just my experience.
My 43 is also on order, can’t wait.
Our GLC 63s will be about AUD$180 - $195k, or approximately USD$121- 131k.

I love my 43 and I have no regrets at all. The 43 is an awesome ride. In the uber rare occasion where you are drag racing on public roads and there is a 63 next to you, you will lose but are people really drag racing their mom wagons or taking it to the track? Why? lol.




With that being said, if money was infinite I'd get a 63...but then I'd also have a Huracan, Pista, and a Urus in my garage.

Our optioned GLC43: $76,200.00
Comparable GLC63s to our options: $104,800.00
Now you see why for me, the $30,000.00 jump wasn't worth it at the time? For a tune, I'm closer to the performance of your standard GLC63 and literally drive the identical car. Most people can't tell the technical differences of the two models. Both are fast and both look great. If the difference was only 10K like you guys in the States, then I would have jumped all over the 63. Me adding the 63 front fender flares cost $2000.00 alone.
