Hi there
I’m lucky I get to drive and write about such stuff and did an article on the GT’ S kindly lent by Redline a while back
It’s a fabulous car a nice balance of quick and comfortable the cabin is a tad cramped mainly due to the large centre console but that adds to a cockpit feel fit and finish is excellent and it sounds epic.
However it’s an option sensitive car so if you can get a loaded one and the glass roof is a great option to have.
Now then my brother bought one a 2015 car low miles nice spec and adores it however late last year at 15000 miles he saw oil under rear on path he took it to MB who said the gearbox which is transaxle needed replacing which as he was 3 months out of warranty would be £16’000 !, after 3 days of heated debate they agreed to pay as they have had a few go so a ‘known concern’.....scary stuff
Anyway he got it back and it’s been faultless since.
So yes great car but either buy one in warranty or take out MB warranty via MB direct and renew each year circa £800
Hope that helps
