Not a bad price bud, and milleage is still low. And still in motorplan, so a good deal.
I bought my E90 2010 N55 LCI with 62000 on the clock for R280K
Make sure they replace rear tires if they are shot but they will anyway if its from a BM dealer and give the car a full checkup, check what was replaced under motorplan and ask to get a quote now to extend motorplan, theyll give you better price now instead of asking just before its ends.
Other than that, milleage is good, and if the car has been looked after it shouldnt have any kurb rash or buckled mags.
Good luck with the purchase bud.
