Purchase decision XC70 P2 or P24

Hello, I need your advice or your assessment / experience about the XC70 D5 AWD: I’m an absolute newcomer in terms of Volvo. I’m looking for a Volvo XC70 and I’m still swarming back and forth between the first generation (BJ 2004-6/2007) or the second gene (from 2007-2009). Don’t need a lot of snappy equipment, and just want a heightened combination with all-wheel and high-quality materials that I can drive for a long time. 30k a year. The question is, would you rather say that the older models have better / higher-quality materials installed (i.e. motor / gears etc.) or are there almost no differences between 1. & 2. Gen? Find price-wise they give almost nothing if you want to spend around the 5-8T€ so you can find from 220T km which are in the price class. The consumption should be even lower for the older ones, which is noticeable on any case also at 30Tkm a year. Would you be happy if you could give me some tips / advice Alex!
