Unerstand where you are coming from but be careful not to jump out of the frying pan into the fire with a discovery. The discovery is a new model and I bought a discovery sport again a new model in April 15. I am changing my car and going for a GLC as you wouldn't believe the issues the Discovery sport has had, have a look at there forum. Lots of them have been rejected because of quality issues and Land rovers response is about as good as Mercedes. Hopefully the D5 will be better but somehow I doubt it.
