I have had the GT hatchback since new in 2010. It came packed with a plethora of accessories -however one item ( the Temperature Gauge ) I have wanted to install but never did because ....I didnt want the car to start looking cheap or..... I was to lazy - . Its time now since shes gettn long in da tooth- 150K - Im looking for one which is easy to install and blends in without looking cheap or shade tree wired. I have trouble understanding why Mazda put an idiot idiot light into the 3s which in my opinion are sports cars. I think at least the GT should have one....but hey ...... Its a minor thing , if anyone has a brand recommendation or kit - I would be extremely grateful. I obviously prefer a well made high end product - but it may be a $10 deal -?
