Help with car purchase !

Good day ! I want a new used one. Large, comfortable, elegant, … So – now I have come across a Laguna Grandtour BJ. 2002. It is very good optically. I also got a test drive – very satisfied. THE PROBLEM about the thing is that something with the steering (probably servo) is wrong. In the stand very difficult, however, one gives gas and drives, goes again everything. The data: 92,000 km EZ 01/2002 2 previous owners (+ day registration of a car house) 1.8 16V – 120 hp Partl eder Elektronische Helferchen Karte statt Schlüssel 8-fach Alubereift TÜV/HU bis 01/12 Now I would like to ask you – is the model recommendable, or there are things that should stop you from buying. Besides, I am looking for someone in the circle Höxter / Holzminden who would agree to take a look at the car with me and then take a closer look at it. Of course, the most beautiful would be the absolute Laguna 2- Freak or a Renault-Mechanical Greeting
