Cultus is good in his time, cultus is 1990 swift, can you believe it still selling hot in 2015 ?, Cultus has stiff suspension, WR suspension is more like alto. Cultus is no good today,If we apply the story of Cultus for WR, can you imagine getting same Wagon r in 2035 ? it will be worst decision to get one then.
Cultus AC does not even throw cold air if its dashboard is hot, no insulation is there. WR with hottest dashboard throws cool air. Cultus door cannot open 90 degrees, which is must for old age people to sit comfortably and to carry luggage. No Power steering, less powerful breaks. Even Head lights of WR is better, it covers good ground both on high n low beam. Set the Engine aside there are lot of things WR is improved over cultus and that is because of the years of gaps in technology that both vehicle is based on. And guess what one can get all this in less price.
