LOL! I wasn't always as 'savvy' as I am now. I mean, I knew how a car worked, but I always had my brakes done for me, etc. You know what they say; A little knowledge is a dangerous thing!
I broke my first timing belt at 120,000 miles in my 'Hachiroku'. Luckily, I chose the right car, since the 4A-GE engine is non-interference! Throw a new belt in and off you go! (I still pay someone who KNOWS what they're doing to do this!)
Not the Honda. That was the Wife's car. She took it in for service when it SAID to take it in foe service. Good thing, because at that time, I didn't know about Interference engines, and if I had broken a belt in the Honda, I'd at least have been buying a new head, or possibly a new engine!
The other old saying: Ignorance is bliss (In her case, her 'ignorance' of cars dictated her bringing it in for scheduled service!)
That's why I mentioned about the 'wife' having the Honda serviced! Been there! ;)
