For one, they're more spacious and stylish. They have higher acceleration than the Vic as well as a higher top speed. There have been many restoration efforts made to restore the old Caprice police cars that were retired. I've done a lot of research, and I just believe that overall, the Caprice is the better vehicle, and even many of the officers who had them when the were forced to convert to Vics have high regards towards the Caprice concerning their performance and roomy interior. I'm never personally tested a Caprice against a Vic, and I've only owned a Caprice, but I've done my research and I'm pretty sure that if it came down to a show down between a Caprice and the Vic, the Caprice would at least beat the Vic in some categories. Not to mention the Vics had issues with rear-end explosions. Keep in mind that I'm no professional, and feel free to bash me all you want.
