Bought a certified Bmw from here ... the car was smoked in which was not disclosed and rather hidden until the day after i brought it home .. it reakes heavily of smoke .. they then told me they would pay for an ozone or ionizing treatment .. it is 3 months later and I'm still awaiting my reimbursement and no one calls me back .. next step is to talk to Bmw Usa
