The Volkwerks team is Top Notch.
It starts with Jeremy and his attitude towards his customers. He takes his time explaining what needs to be done and if there is a more cost-effective solution - he will let you know. I bring my B5 A4 1.8T and it's always well taken care of, not to mention a savings of over 50% compared to what the dealership charges. They do not skimp on parts either, they use quality parts only, OEM or higher. Their specialty are working with VWs, but they are great with Audis as well. Great place.
