I have a W Reg GS 300, I have only had the car a month and very pleased with it, But as soon as you hit 20 mph I can hear a humming / Droning noise which seems to be coming from the front of the car. It has only done 43K miles so dont think its bearing noise or tyres as these have all been replaced.
Has anyone else experienced this problem and if so how do you fix it.
Many thanks in advance
