Jackportia - I don't know the exact mileage of the Boges that were on my car. It's a higher mileage car, and there was no documentation of a shock replacement... but when I pulled out the Boges, they didn't look all that old - especially the rears that are exposed to the elements, still looked pretty good. I know that is a poor way to tell how old they were, but I'd guess they'd been replaced at some point, no way to know how long ago. Sorry I can't be more helpful on that aspect of things.
I will say this - I replaced them because the car didn't handle as well as I thought it should. After the HD's and the suspension work - Wow!
