It was a little bit of everything this week at Sound in Motion. First, we enjoyed the company of this stunning, fully restored 1972 BMW E9 that stopped by for an audio consult on a different car. We also got to work on this Ineos Grenadier, which now leaves us with a new audio system and 360° camera, while a unique Mustang RTR is in the process of a full audio makeover.
