Oh I know paranoia alright. What with driving an Elan daily to work etc AND flying my light airplane (4 seat Grumman AA5) over to Northern Ireland and up to Shetland fairly regularly, One got a bit keen to listen out for any 'missed engine beats' (just a bit of carb ice) Didn't half wake you up though!! Other than that I never heard it miss a beat in over 400 hrs of flying it. I got to the stage that I just never told it where we were going. It never knew it was over miles and miles of water.
Happy and sadly missed days I admit.
Paranoia will do you no real harm. Helps keep you awake eh?
Above all, enjoy your car. Have fun...
