Hallo noch mal an alle, 
  
danke zunächst erst mal für Eure hilfreichen Hinweise. Es gibt da ja wirklich so allerlei zu beachten und zu bedenken; Ohne nennenswerte Grundkenntnisse und mit meinem begrenzten Budget scheint mir das ein fast aussichtsloses Unterfangen zu sein.  
Verlockende Angebote finde ich dennoch immer mal wieder, wie z.B. dieses hier:

auf meine schriftliche anfrage, ob der Wagen unfallfrei sei, bekam ich folgende Antwort: 
  
Good evening,  
The Audi A2 1.4 TDI is in perfect condition inside and outside as well. I never smoke in it and i want to sell it to a serious person who will take very good care of it. The car have the steering wheel on the left side because is an european car , have German plates. I am located in Ireland and i want to sell it because i need one with the steering wheel on the right side. A car dealer told me to try to sell it on this german website because i can find a lot of potential buyers from all Europe.  
The price that i'm asking for this great car is 5.000 Euro including all taxes (shipping & insurance). If you want to buy this car wich is extremely fast and dependable and also fun to drive then don't miss this unique opportunity.  
I only take in consideration those buyers who are really interesed in buying the car, to be sure that I don't spend my time with endless disscutions,or pure curiosity.  
Thank you and i hope we can make a deal together !

Nun ja, eben sehr verlockend, aber Ihr sagtet ja schon: Bei solchen Angeboten immer VORSICHT, oder?
