DETROIT (WKZO) -- The cars and the crowd will be looking their best at the North American International Auto Show Charity Preview.

Ticket sales for the black tie event have surpassed last year's total and organizers hope to raise four-million dollars for several southeastern Michigan children's charities.  Those attending the preview will be entertained by aerial performers, the Union Avenue Band, and a surprise performance by a home town artist.

The Auto Show opens to the public Saturday and runs through Sunday, January 27th.
