Is it well maintained? Owner keep maintenance records? Or all maintenance done at dealership? 100k miles really doesn't mean as much as it used to. A car well maintained can last much longer.
I will not be purchasing it unless it is well maintained of course, but yes the answer I was looking for was what you said, that 100k isn't that big of a deal.
If I buy it with a manual transmission, I have realized that they have come with the CD player and not the AUX. Are they any mk5's that come with a built in AUX player from the factory that is a manual transmission?
