I had this Interstate for about 4 years (or a little less), and my service
station (that I'm into for some nice cash due to tune-ups and brake jobs!)
wants to see me an AC Delco 58R for $105 including the simple install.
I've read that the Probe GT goes through batteries every 4 years and I've
been through 2 now as I'm the original owner.
It appears that batteries are impossible to order over the net and most of
the distributors are service stations.
Any recommendations? It seems that Interstate, Motorcraft and Delco are
about the only batteries that people are using for this car. I don't think
there's a Sears Diehard in a 58R.
