Extra guages mean extra things to worry about.
Very true..... but for me gauges have saved me more than one engine in the past.
Agree. They have for me too. You just have to find the right balance between having a nice drive whilst concentrating on the road, occasionally glancing at the guages, or constantly watching the guages expecting something to happen, therefore spoiling your drive.
I often get asked, "Why have you got a voltmeter?".
"To see if the alternators working", I tell em.
"Don't need one of them in my car, and my cars got an alternator", they say.
