You would not believe how accurate ^^^^^^^ this statement is....

Downright scary.
I wasn't able to get an accurate 0-60 time as my wife yelled at me (for real) for spinning the tires attempting to launch the car.
Turns out the cake she had just finished was still in a "delicate state" and didn't like to be thrown to the back of the car.
As to the gauge. The digital MPH readout was dead-nuts with the cars' speedo. The needle however is a bit "lazy" and reads a couple of MPH lower than the digital readout. Not a big deal really. Other than that, the GPS speedo worked fine.
On the drive home, I got to test the brightness of the needles and I'm not impressed.
I ordered WHITE needles that are supposed to glow ORANGE at night. The car coincidentally has the same setup(white during day..glow orange at night) and the cars needles are BRIGHT! So I had something to compare it to.
The Speedhut needles have a very dull glow. Good enough I guess, but once again... Not even close to what is shown on their website.
Still a cool gauge though.. Is it worth $450.00?
Probably.... Had I known then what I do now, I would have ordered orange needles and made a few other changes.
I'll also state that their customer service has been excellent to date, and that in and of itself is worth $$$$$$$$$.
Now to make a mount.
