My "friends" ask me to tow their cars on occasion.
No thanks, not interested in being responsible for towing or safely strapping down your GT3 in my trailer.
Another reason to have AAA roadside service is for when friends call for a tow.
I offer them one of my AAA tows.
When my wife had a flat tire on the freeway I'm OK that I don't have to go change it.
Or when my 1 ton truck towing a trailer had a flat on the busy 5 freeway while crossing the grapevine, very nice to have AAA change it.
AAA sells Interstate batteries delivered/installed for the same price as Costco.
Have used the AAA DMV and travel services too.
