  A specific class of singularity free cosmological model has recently been
considered in light of different observational data like Observed Hubble Data,
BAO data from Luminous Red Galaxy survey by Slowan Digital Sky Survey (SDSS)
and CMB data from WMAP. However it is observed that only $12-14$ data points
are used to study the viability of the model in late time . In this paper we
discuss the viability of all the models belonging to the same class of EU in
light of Union Compilation data (SnIa) which consists over a hundred data
points, thus getting a more robust test for viability. More importantly it is
crucial that we can distinguish between the various models proposed in the
class of solution obtained. We discuss here why with present observational data
it is difficult to distinguish between all of them. We show that the late time
behaviour of the model is typical to any asymptotically de-Sitter model.
