Thanks. It's been a tough summer. She was 48 and I'm 53. I drive a gas pig Lexus GX. Finally came to the conclusion that most of the gas savings was offset by insuring 2 vehicles. I need the GX(or something similar) for towing a boat.
Yeah, looks like you're stuck with the Lexus, although some here have used the Prius for towing large objects: Towing? | PriusChat
Weather permitting, a/c and heater off and windows down. You can sit there for hours without using a drop of fuel!
Or if you're completely at a standstill, just shut it off. The only issue tho: OP say's it's raining bad, would get all fogged up.
Sell the car. I was in a similar situation and having her car around all the time was a constant reminder.
Sorry about your wife. Re the Prius. If you or a future owner need/want to stay in the car, it makes sense to should leave it on to provide heating or cooling as needed but leaving enough gas to get to a gas station. It won't use much gas just sitting there. From what I recall, it may be able to run for days depending on how much gas you have and how much cooling or heating is needed.
