Neighbour fixing cars

I have a neighbour directly beside me who works on cars out of his driveway. Last summer it was every evening he would be blaring music, banging, just general mechanical noises but this goes on all hours of the day and late into the night. Now that warm weather has come, he has several cars parked outside our property at all times so he can fix them at all times, is blaring music when fixing people’s speakers and lastnight he worked on a motorcycle and revved it on and off for over 30 minutes. The logical thing to do would be to ask him to keep it down but this is clearly his side hustle and I don’t know how he would keep the volume down. You would think that something like this would be a common courtesy considering he’s not working out of a garage just a driveway, a couple centimetres away from mine. any suggestions on how to go forward without seeming like an asshole but also not risk losing my sanity?
