OK, OK, I admit the reason I want a gauge is the "bling bling" factor... but with what Mazda has on the car already I'm having a tough time making any super "meaningful" improvements.
I got a round shift knob because I like the round knob (ichiban, JC Whitney, orange leather over aluminum, $29, anyone want to buy a Sparco?), I got a trailer hitch (see other thread) to mount the bike rack... hmmm... 120' of thin orange pinstriping that I haven't gotten around to installing and may never (anyone want to share? I've got enough to stripe a semi truck here...), Fiamm dual tone horns (no more Roadrunner meep meep, a "worthy" upgrade) and that's about it!
Only other thing I'd change would be maybe a CAI but only once we get this hesitation thing worked out (see OTHER other thread)...
