It was a 2003 Toyota Camry Solara convertible. It had major electrical issues, gremlins that no dealer or mechanic was ever able to sort, despite happily taking my money for never fixing anything. It went through 4 batteries and 3 alternators in maybe 10 years. It left my wife and/or me stranded countless times by working fine until we got to a place, and then simply not starting when we wanted to leave.
My experience with and basic knowledge of electricity tells me this was quite possibly a grounding issue, and some of the various mechanics identified it as such on a couple of occasions, but nobody was ever able to actually correct the issue.
Good Lord I grew to hate that car. I was so delighted to trade it in and exchange it for the notoriously unreliable Jeep that replaced it. We've now had that Jeep for 5 years and not one single issue with it, just standard scheduled maintenance.
