sorry, i have qualified this before on the forum but to summarise,
they fitted a flat tyre to the 5 series bmw, then used two rings of weights to offset it, stop a second and think about that, have you ever seen an alloy with 2 whole rings of counter weights!
they then refused liability that the tyre shredded itself when i drove it,
then argued with the place i got to rectify it suggesting i wouldnt get a refund.
managed to get one in the end but i would never use them again even if they paid me,
as others have said, the only thing between you and the road, once bitten etc...
just a big bag of clunge their whole company...
