GLS vs GL63
I've been looking to get back into an AMG and have been following the GL63 for some time.
Yesterday I dropped the wife's car at the dealer for service and they gave me a brand new GLS550 4Matic as a loaner.
This thing hauls. I'm driving an X5M, and I think it's super fast, but man, I am thoroughly impressed with the GLS. I think the most impressive part is how it gets up and goes for the size it is. Of course it's not as fast as my M but I tell you, it's plenty for what it is.
So the question is:
Do you buy a GLS550 or is the GL63 still the one to buy? Why?
How much power can be had with a tune on the GLS550?
