I feel for you..... I left my trusty old Zefal HpX pump in the trunk of the car I traded in 10 years ago. That pump served me well since I bought it in the 80's.
So excited to get the new car home and get rid of the truly evil one it replaced (1997 B4 VW Passat GLX VR6) that I forgot I had it back there hiding in the dark recesses of the trunk, with it's satin black finish....
I'm still kicking myself for losing that one, even after a decade already......
I figure it was the Passat last kick to my groin on it's way to the junkyard after only 70K miles....
