Luxury brand slices more than $10,000 off Audi Q5, BMW X3 and Lexus NX rival: 2025 Mercedes-Benz 300 GLC 4Matic Avantgarde available in limited numbers until the end of the year as three-pointed star's cut-price Christmas package

There’s nothing like the heat of competition to sharpen a carmaker’s focus as the run towards the end of the calendar year approaches.

So, the three-pointed star introducing a new value- and design-focused variant to one of its most popular model lines at a price that lasts until, you guessed it… December 31, isn’t a huge surprise.

The 2025 Mercedes-Benz GLC 300 4Matic Avantgarde brings a solid specification list to the party as the premium mid-size SUV attempts to catch its BMW X3 nemesis, maintain an edge on the Audi Q5 and put a dent in the category-leading Lexus NX.

Available in “limited numbers”, as the name implies this new GLC 300 option swaps out the standard AMG Line styling package for an Avantgarde Line treatment. 

Priced at $99,900 drive-away the new GLC 300 Avantgarde grade represents a roughly $11K saving over the 'standard' AMG Line model ($111,000 D/A, depending on state/territory).
