Hi 74RR. I've never personally owned a Dynamic, but I can confidently say from all the rave reviews I've seen and heard over the years, that the're a top notch company with a top notch product.
My slight concern is that it's a used unit. Not from a quality standpoint, but from a application standpoint.
I'll just make a suggestion here. Most of the big name companies keep a record of all the units they produce. Mainly so they know what the're dealing with when one come in for a "tune up". I'd get the previous owners name, if he's the original, and any numbers or stampings on it so you can call them. Many 9.5's are built for so many different combo's, that if you give them your combination info along with the unit numbers, they can probably give you a pretty precise idea of how it will react in your car.
I'm sure you're gonna love it. Take care, Rick
