 However, in the back, the Veritas shares the Buick Park Avenue's electrically adjustable, heated and massaging back seats, along with the same flip-down centre console with seat controls, and the same single roof-mounted DVD screen fitted for rear seat entertainment.The Veritas gained its own unique features not used on other Caprices, including an internal air purifier system, power-folding side mirrors and an extra bank of navigation and infotainment controls located near the shifter.The sole powertrain on offer was the 3.6-litre "LFX" V6, later upgraded to the direct injection "LLT" version in 2010.
