Volvo V70 or S80 short bearing if possible

Hi guys, we’re currently driving an Opel Omega 2.0 16V Bj 98. We’re looking for a Volvo, we’ve already looked at a V70 with 170 Ps and 2.4 liters. Nice thing so with climate, leather, glass roof, heater, E-seat and so Bj 2000 and 168Tkm on the clock for 7500 euros. The H.ändler also had a Dekra expert report, I don’t give that much. Today we’re looking at a S80 Bj 10.2001 with also 2.4 liters and 170 hp. He also has leather, climate, car phone system, and Radi/Cd HU 6 01, DSTC and Tempomat etc for 5800 Euro ach ja 156Tkm on the clock. What should one pay attention to, what says the verbauch are both automatic 🙂 should be so desired. What do the parts do so, rust etc. Would be grateful for any answer and help. Lg Martin
