This is Prosport's best gauge to match the MINI lighting setup, and if I may add, they look amazing!! I breifly installed the gauge itself in the center console gaugepod to see what it looked like but the harware is brand new, never installed.
Asking $30 shipped for just the gauge ($38+ship retail)

I also have a oil pan gasket avaliable for tapping the oil pan, if thats the way you wanted to go. If you drop the pan to do an accurate tap, you'll want the oem gasket to replace the old one.
Asking $70 shipped for both gauge and gasket (gasket was almost $47 through minimania)
