I believe there was more than one vehicle used in filming -- go back to Episode one at the opening sequence; when he enters the car thats obviously the steering wheel from an 06-07 model that you can see from the interior angle it was hard to see if it had the fugly side vent..
Now let me draw attention to last nights episode -- after visiting the 'informant' and the passenger side angle of the dash when they entered the car the trim on the dash was wood -- not aluminum but had the V logo (odd didn't know that was possible) and the steering wheel was definitely a 2008.
Maybe i'm wrong.. or being overly observant as usual
