Renault Megane II: Buy or not?

Hello, I’m in training from 1.8.2009 and need a reliable car for this. Drive about 100KM a day, so of course the consumption is also very important, and the Megane shows itself quite well. Meaning is the Megane from year 2003 on. I don’t know which machine to take, but he should already have 100hp (lover about it). Now the question is, which engines of the Megane last long and whether the Megane is more susceptible to interference at all, or not? Diesel or gasoline? How expensive would inspections be? If you need a few experiences, it would be nice. Thank you in advance LG
