Help with the used car purchase Volvo XC60

Hello dear community, I’m very interested in a Volvo XC60 from 2012 with D3 Motor (163 PS). So far everything sounds great, what the (private) salesman advertised and personally sent me, and I wanted to make a trip (>4h) at the weekend to visit the car. If so, I would buy it directly. Now, however, a few things seem strange: 1. In May 2022 the timing belt was changed at Volvo at 155,000 km – by the previous owner. Cooling water level was also checked. On the bill there is still a finding: ,,,Kühler undicht. KVA attached. Starting flap noises underpressure pump ” However, these works were apparently never done there and this KVA was also not sent to me. 2. After that was also made in the autumn of the same year, a cooling tank, with re-examined, since at the rear the error message has to be bought. No word of the cylinder.
