My experience with music stores has been mostly negative but seeing as Musicmic has drifted a little into auto-mechanics, I'll have to agree with him.
I found Andy Curdo in West Chester, PA. because he was the only Nissan dealer listed. After he had looked after my Pulsar for a couple of years with minimal cost and excellent work, when I needed a new car I asked him. He sold me a Sentra for $1200. He was asking $1400 and all I had at that time was $1200 so he settled for that even though I had asked if I could pay him the other $200 next month.
That was three years ago and the Sentra is still going strong.
