Which SpaceStar Diesel to buy?

Hello guys, I’ve been looking for a “new” used car for quite a while now. I’m currently driving a Volvo S40 2.0l BJ.96 With now 210,000 km on the clock, it’s time for a new car in the medium term. After I happened to see a SpaceStar today, I thought to myself. Hey, that’s what it would be like. I’m alone, but I like to have a spacious car. I don’t want a “big van” and I don’t need to. After everything I’ve read so far, the Space Star seems to be a good compro. My modest budget is between 5,000 and 8,000 euros. If you look inside at mobile.de, you can definitely find something. With the diesel models there is as far as I have now seen 102 or 116 hp. Which of the two engines is the more robust – or there are significant differences? How are you different in the topic of “consumption”? I would also like to know how it is with the vehicles with the topic “End speed” looks? Is there any other thing you should pay attention to when buying? When is the timing belt change due, for example? Would I be happy if you could share some experiences. Thank you and many greetings Skodi4711
