A tow bar is nice for the in town stuff. Worst case scenario, you get a ride home, pick up the tow bar and go retrieve your ride.
I have state farm and they recently told me that I had free local towing (forget the details...) and I've had it all my driving career. Fortunately, the vehicles I've had that break down are always ones that I have a tow bar for so I haven't had to use it...yet!!!
I use my state farm for everything. They told me that my bus trixie was worth a lot more than I envisioned it, so I said ok and spent the first few weeks hoping a tree would fall just right... Now I'd rather keep her. I don't know about Bonnie; we never discussed a value. I should probably ask.
