By using type Ia supernovae (SN Ia) data in combination with recent baryonic acoustic oscillations (BAO) and cosmic microwave background (CMB) observations we constrain a kink-like parametrization of the deceleration parameter (q). By adopting a likelihood approach to deal with the SN Ia data we constrain the model parameters and show that, in combination with BAO/CMB, SN Ia data processed with the MLCS2k2 fitter favors Dvali-Gabadadze-Porrati-like cosmological models, while SALT2 fitter favors ΛCDM-like ones.
