No, it shouldn't be, as I'm not the original owner of mine either. However, don't add fuel to the small fire by going out of your way to tell them this.
You love your ride, present your Touareg nice and clean to them, as though you care about it(which I do hope in fact that you do), and they should treat you fairly.
Make no mistake, if you present them with a 10 year old Jetta, rusting and bubbling everywhere, and you are the 3rd owner, don't expect them to cover anything. Hell, I'm sure if you are even the original owner, and present them with an 11 year old rust bucket, with one more year until warranty expiration, they will laugh you off the lot. Just sayin', there is a level of common sense here that for sure is taken into account in the decision making process.
I don't want to brag, but mine is one of the cleanest, nicest Touareg's in the region. When I take mine to the VW dealership for whatever reason, the techs run out and in awe at the sound and condition of my ride. Their zzzzzzzz 2012- 2013 T3 TDI's take a back seat to my modded 05 V8 upon arrival
