The way i see it; E70 is a run into the ground car now, as much as i like them, @ 8-10k i suppose they make a nice car, but my understanding is that the petrols from this era are easily as problematic as the diesels. Things like seals causing oil burn, this was a big E60 era issue and i believe plagues the E70 as it is the same platform. For my wife at ~£10k i bought an F25 X3 M-Sport 3.0 diesel instead which i thought was a much nicer more modern car. At twice the budget they are completely out of the question imo.
Q7 agreed, way too dated, similar story to the E70.
By far the best cars for this budget are an F15 X30/40d M-Sport, or a Cayenne 92A 3.0, or actually you might even find a 4.8 petrol. These are really nice cars, probably nicer IMO than the F15, certainly better built and feel more premium than a BMW. Smaller though than the F15.
