I've been told how great looking I am but deep down inside I'm rotten to the core. Relatively inexpensive and easy to check those cables.
The top half of my engine bay is crazy nice. Look almost factory clean. I dont know what the last guy did to get it so nice but all my cables are in great shape.
Sorry, using a little sarcasm to back up what Sasquatch suggested.The terminals and ground at the battery are so clean you would be shocked to know its 21 years old.
