The 5x110 size also opens you up to using wheels from the current Epsilon-based Saab 93 and Cadillac BLS. As well as from a few american cars like the Chevrolet Cobalt SS Supercharged, and Malibu, Pontiac G6 and Solstice, Saturn Ion Redline, Aura and Sky. (not sure of the ET on all of them though, the Malibu, G6 and Aura would be good because they are Epsilon-based like the Vectra)
