Nothing like cool cars to crank up the heat. Wednesday evening 30 vintage chassis lined up in front of Bossa Nova, Downtown, for the Pittsburgh Vintage Grand Prix's Tune Up Party. Drivers, sponsors and racing fans joined host Robin Fernandez at his night spot while they checked out the cars and chilled inside with drinks and a buffet of appetizers. Chaired by Lynne Figgins, Michelle Polaski and Helen Wylie, the party included a silent auction and a performance by Latin Grammy nominee Kenia. Pittsburgh artist Tom Mosser painted a picture of a Mustang during the party (this year's Marque car), which was auctioned off by WTAE's Andrew Stockey. Among those getting in gear for a good time were honorary chairs Dotti and John Bechtol and Rosemary and Joe Mendel, Bob and Janine Fragasso and Duncan Neilson.
