Yar i think Vitz also came with a digital meter bt just b4 the new(spider) shape, i guess it is 2004 model, since 2004 vitz are less common(most ov them are 2000-03 models, they dnt have a digi meter.
Yaris comes with body kit and nothing extra as compared 2 vitz...
And possible Answerof ur question tht why not vitz? is..
To please luxury and style loving Arabs, toyota had no option except presenting their car more nicely.. So they gave body kit there..MayB?
Bt yaris is arabian & usually comes repaired/reconditioned and vitz are genuienly kept japanese ones so here Vitz has more market than Yaris.
Iv got a ride in both no visible differnce btw both.. both are awesome art work and gr8 engineering! Just love them!
