I have a set of General Exclaim UHP's for sale. Less than 1000km's on them. Fits your OEM mcoupe, mroadster rims. They ride more comfortably that the OEM ContiSportContacts and are of a softer compound which offer more grip.
Fronts 225/45/ZR18
Rears 255/40/ZR18
I am selling them because I am trading my car in early and I will return the car with the OEM ContiSportContacts, which I have in my garage with JUST enough tread to pass inspection.
$800 (CAD) for the set (paid $1027 less than 3 weeks ago)
I also have a set of Continental WinterSport M3's which fit the OEM rims. less than 4000Km's. Yes I drove my mcoupe in the winter. Was actually better in the snow than my old 5 series.
$950 (CAD) for the set (paid $1444)
Also, OEM car cover available.
$250 (CAD) (paid $500, barely ever used)
Local pickup is preferred. I am in Montreal. A friend of mine also goes too and from Toronto every few weeks and I should be able to have him bring them down.
Otherwise I can organize shipping at your expense anywhere as long as I am paid up front.
