Buying a car……Renault Laguna 2 or Peugot 407

Hello, at the moment I drive a Laguna 1 Grandtour, 11years old. Since I need the car now daily and the car already has some defects I wanted to buy another used one now. Budget max. 10000,-Euro. Now I like the following models of the optical quite well…. Peugeot 407 or Renault Laguna 2. Both as a combi, I am not yet clear about the motorization, however, should be a diesel with a Russian filter and a little over 100hp I think. Which engines n can be recommended? Well my question, are there any defects/weaknesses in these models what you have to pay attention to? Which car might be more recommended? Thanks for your tips….. Lars
