'High' mileage on 2008 A4 3.0TDI Quattro

[rich12]

I have been looking at A4's for my misses and was originally looking at B7s but have noticed a few B8s with over 100k fall into my budget which we both prefer.
The one in question is this one,

They have a much better spec than the older ones and in general seem to be a much better car.

She will only do >8k a year so won't put a lot of miles on it in the time we will have it but am I better going for an older lower mileage model???

I know the mileage isn't much for a diesel but the petrol equivalents are a lot more money/rarer.

Thanks
