Incession Z3 M 321PS

hello municipality I stepped on this little sweet ///M occasion at a BMW representative 2 days ago “see below”.(Switzerland) Logically, the seller can only tell me good on some of my questions. But it came to my attention that the engine is not the yellow of egg ?? or … power without end, but many capital engine problems. The ///M comes as a second car, as fun car just (holiday, weekend) But now I want to have some input, especially with regard to the engine. I don’t care if the CD system or a turn signal strikes! Small stuff! (I also get a sniff every now and then, the main thing is that the pump doesn’t flute) :-)))) Vehicle type Occasion : Traffic 5 / 1997 Kilometer : 82’000 km Gear type : Hand-circuit Internal colour blue Engine capacity in ccm 3201 cm3 Cylinder 6 Power in PS 321 !!
