Like Marv said nothing we can do to take away the pain...
But just for reference my dad also just past away and mom is 90 and... well.. things are getting weird.
There is no beloved heirloom like your dad's 911, but dad was a good businessman and set up a living trust.
Mom is comfortable in the house with a caregiver and is trying to give everything away... not to be disrespectful but it is kinda creepy... she has a very nice house and some nice furnishings but we have all agreed to not accept anything from her (nor are we interested in the 1980's vintage furniture) and settle accounts after she is gone.
I'm rambling so back on point... maybe it was a bad memory for your mom so she just wanted it gone (like why my mom is trying to clear out her house)... why she didn't give it to you to get rid of it I can't say.

Hang in there, You will find your car.

PS, Again, not to be disrespectful and I don't know your mom's age but my mom is becoming very erratic in her old age... the reason we are not taking her up on any offers for instance: she gave me her old cedar chest (that is crusted with old ugly yellow paint my dad slathered on it). I had the intent of stripping off the paint and using it in our bedroom. A few days later she asked if I was going to sell the chest (oh my... I could probably get all of $50 for it!) and if so she wanted it back. When we first got a caregiver she threw all the caregivers belongings out the front door and called the police. The list goes on but you get the idea... age/health/meds can make the elderly do some strange things.
