No car is perfect, but we've gathered everything relating to the Smart reliability here to help you decide if it's a smart buy.
Is my 2006 Smart ForFour affected by the airbag recall?
No, the Smart is in the clear on this one.
THEY have a basic responsibility to deliver a professional service, and it seems they haven't. You should complain to the company so they can take action to make sure it doesnt happen again. If that doesn't satisfy you, find out if they're a member of a trade organisation and make your concerns known to that body. You could also report your problem to the manufacturer/distributor of GT Radial tyres so they can take action. Finally, go to your state consumer affairs people and lodge a complaint.
