dont think klms would say much - if the car drives well, then thats all that matters. Mine supposedly had 73,000 when i bought it (96 R33). 7,300klms a year? I didnt trust it, but went on the overall feel of the car and how it drove. Its probably done more like 150,000klms.
If you are thinking of getting the 34, then get a full test done at a performance workshop - thats the only way you will know if the car is a dud or not.
No idea about the tiptronic though - but from my experience driving other cars with tiptronic - i find them to be a waste and they divert your concentration from driving the car to focusing on changing. Manual FTWl!
