Bike Forums - Looking for advice - Lapierre tecnic 700 hardtail 09

Hi there,
I'm thinking of taking up mountain biking and was looking at a few bikes today. My budget was in around the 500-550 mark - a beginner bike. You could tell the quality wasn't great on these in the shop though especially compared to more expensive ones - cheap plastic pedals and gear levers..

There was a used Lapierre (model in title) though that was 650euro but he will give it to me for 600 euro. I can't really find any reviews but it feels like good quality and would have been about 900 new. It has xt back derailleur and slx on the front.

Any advice or info appreciated before I make the decision. Thanks.
