Very serious the car I am talking about is the blue M5 standing at Monte Carlo Auto. The work under motor plan was done by JSN Motors.
New engine has done 700km..........
Ok, went out car looking with the family yesterday, and bought a e90 330 with 40000km it's a 2007 model with 6 speed manual. As much as I love the 550 the tiptronic is not for me.
There is a manual one for sale, if anybody is interested pm me, I am convinced the car has a engine problem, as it does not sound right, and has no power.
