Now I think I know the answer but people tend not to believe for some reason or another. My friend has a 2015 BMW 428. He recently went to start after sitting for a while and the battery was dead. Anyhow, I told him to pick up a trickler and said you can find pretty cheap. He wants to buy a BMW one because he is concerned there is some special BMW technology going on.
From experience, with my 00 Boxster I was have a cheap one that has been working fie for years I (I think harbor freight). Should he pay the premium or is he okay with a cheaper one.
This guy also took his Volvo to the dealership for Volvo air when his tires were low.
