Here's a review from Standard.co.uk on the Mercedes-AMG GLC43 Coupe.
Review: Mercedes-AMG GLC 43 Coupé | London Evening StandardBut when you get out and look at the beast, what are you getting for your money? Money which let us remember is another £3000 on top of that of the GLC 43 SUV. You are getting better handling, that’s true, but performance and everything else remains the same. Except for the space. That new bodywork means less room for people and their luggage. It’s not a small decrease either – boot space is down 200 litres.
