I don’t know if I would call it high mileage with 80tmls in 9 years the car was on the road in his life , I drive usually 25-30tmls annually.
When the ABS system kicks in is a puffy noise because is vacuum operated I had too try it in a gravel backalley
Interesting the sounds it makes. You should make a video in all your spare time.
Those must be "highway" miles then. I am used to seeing so many garage queens with crazy low miles lately, that was all. Great that everything works on your Imperial. That really makes it worth more compared to most Imperials that usually have lots of issues to fix!
