I had a beautiful blue Mustang. Followed the severe duty preventive maintenance plan out of an abundance of caution. Thermostat housing cracked, stuck on a hill, in construction, no shoulder. Ended up cracking the damn block trying to get out of people's way. I had a kind of shitty silver Sonata. Kept it on the severe duty plan. It just shit the bed on me with ~130K miles. Getting old fast.
