well i get 10mpg with the S8 badges on
and 40mpg with them off
im so confused
Anyway.......
that 4.2 tdi engine is without doubt amazing..
but less mpg and the £500 tax disc..
if you want spec you would buy mine..
if you want that 4.2 engine then go for it, i wish i had..
that particular A8 has not even got Bose..Boring..
the B&O was £4500 its worth a grand extra now on any secondhand A8..
