When it's time to let her go...and how?

My poor girl. Purchased in Chicago in 2014, she was a 2005 with only 60k miles on her. Owned by an older couple who drove infrequently. I put 80k miles over 10 years in hard Chicago winters on her, and now I think my time with her is finished.

Recently had a new axle installed, and then 2 new ball joints just a few months ago- neither shop mentioned the entire frame is rusted. Couple weeks back the check engine light popped on and code P0446. I followed a lot of advice from this forum, tried closing the gas cap tighter, cleaning off any residue, etc.. After several months of the code coming back every few weeks, the red triangle popped up.

The dealer says charcoal canister and purge valve need to be replaced- another $1100. I just don't have it in me. After this i know the shocks and struts are waiting in the wings, the spark plugs are still the originals, and the hybrid battery at some point. The bumpers are both cracked, body damage to the side from my genius exboyfriend telling me I had clearance when I definitely did not have clearance. Interior is forever stained by my anxious cat causing me to spill an entire travel mug of coffee on the back seat when we moved. She has been very well loved, a little too well loved.

Question is - with a bum charcoal canister and purge valve, can I continue to drive it? Was considering doing these myself and my dads help - he was under the car earlier to get an idea, which is how we found the rusted frame. I'd like to at least drive it to dealers to look at other cars this week, and then be able to trade it in. Toyota offered me a trade value of $1k- heartbreaking!

 

Thanks - my confidence level is higher with some parts of the car than others in terms of repair. I did order the rear taillight and replaced that myself a number of years ago, this one is outside of my limited skillset. While Illinois did not have inspections, last summer I moved to Maryland which does. At this point, planning to upgrade to a Subaru Forester and keep the Prius as an extra car to drive locally for the time being. Thanks for your input!

 

Thanks- I thought so as well, except after I got a full tank of gas the last time, the red triangle popped on and my heart sunk. Fortunately when I cleared the lights, that one cleared as well- while the check engine light has come back, the red triangle has not, so hoping this car remains drivable as a local car for a few more months.
