Can anyone recommend a shop for wheel balancing that they've had good experience with? Ideally in eastern MA but Id be willing to drive a bit further to a place that's well recommended.

I have a new A4 that has seat vibration at certain speeds. The dealer I bought the car from has replaced 2 tires and balanced all the wheels. I'm still feeling the vibration. (It's better after the tires and balancing but still present.) I did a long test drive with a tech last weekend and he claims the vibration I feel (which he also noticed) is road unevenness. I disagree, so now I'm looking for second opinions on the wheels.

I appreciate any suggestions!

Edit: I found an older thread where someone recommended Auto Engineering in Lexington (https://www.autoengineering.com). That'll probably the first place I call and it's one town away!
