I have oil, temp, and knock gauges that are literally NIB that my wife bought from Summit. Got them for my birthday because she rocks, but I wasnt in NEED for them. Granite, I dont have those particular gauges in my car right now, but i wish she would have spent the money elsewhere, ya know? Women are sensitive about selling "gifts," but I'll ask her how she feels about me potentially selling them. Wish me luck!! If she's cool with it I'll let you know.
