cracking big cars those E38's!! looks not too bad condition either?? Though 2.8's Achilles heel is it's radiator/ water pump and head gasket. So keep an eye on that temp gauge. Should never move above the half way.
Also do you know if the gearbox oil/filter has been changed? as BMW states those ZF boxes are sealed for life, but ZF's version of for life is "100k miles"!!! And they do go pop easily.
you can generally get it done for about £150-200, money well spent if you want to keep it running!
I just picked up a new car recently as well an A6. 2.7T Quattro tiptronic. absolutely love it, it just reels in the road!!
I'm loving it so far, last owner bought it just to drive to Spain and back, i can understand why
Condition is ok, front end is quite bad with stone chips, the mirror cases are scuffed and small scabs of rot in the rear arches so will maybe get a part respray in the spring, interior is superb though.
Water pump was replaced just before i bought it, rad looks ok, temp never goes above 1/2 (have had to bleed it a few times due to the heater valve etc), should be ok for a while but i'll keep an eye on it.
Funny, i was thinking about a gearbox service the other day, have read about the "sealed for life", my car has 160,000 on it, assuming it's never been touched so i'll be getting it done for peace of mind.
Also going to change the serpentine belt and tensioners for the same reason.
It's not been neglected though, has a BMW service history to 149,000 (so was due a service now) so should'nt fall to bits, i've already changed the engine oil and filter (Mobil1 0/40 new life and a gen filter) and gone through the brakes (just needed new front pads)
Audi looks ace
