I recommended these tires to a colleague for his '99 328i, he absolutely raves about them.
Can't wait for these retched Pirellis on our wagon to wear out (soon!) so I can get 215/55/16 950s on Mille Miglia rims.
We have 910s on our 328i and even they are quite remarkable for a low price tire. You made the right choice, far as I can see.
