XC70 [MK1] (2000-2007)
Part of the Volvo V70 range in the second generation, Volvo offered as an all-wheel drive variant marketed as the V70 AWD and as a crossover version initially called V70 XC. For the 2003 model year, the crossover was renamed to XC70.
The XC70 underwent a facelift in 2005 with differences to the dashboard. The later model has an additional trim piece surrounding the radio and climate controls. This trim is often silver or wood effect.
