OK, I'm a still in 2007 or did I just see a lancer commercial saying something along the lines of "Three cars one soul..."
Base
Ralliart
Evol X
????????

You're talking about the commercial that was posted on this forum by KMX?

i believe the 3 cars are:
evo 8 rallicar, a regular lancer gts, and the evo x

saw this commercial twice so far on tv
