Hm, not a clue actually. I know he drove Thompsons old Alfa last year. But my guess is that it is still the same. I can not recall him smashing the car into a wall or anything so switching to a new(er) 156 sounds unlikey... but again, only my guess
I am wondering what will happen if he ever wrecks this car completely. In 2007 during the Brands Hatch WTCC race they said that Tielemans was not allowed to take too many risks in the race cause he drove literally the last 156 there was Complete wreck would be the end of his season.
So lets hope Andersson will not have that bad luck!
