What a sweet story!
I can appreciate some of the feelings - through pure serendipity I found and was able to purchase my grandmother's '62 Thunderbird in 2009. I had grown up with the car in Los Angeles, as my grandfather had purchased it in 1963 (I was born in '68). It was sold in 1998 when she stopped driving. Found it purely by accident on Hemmings online in Palm Springs. I had since moved to PA and it arrived in the middle of the night on a semi car carrier. I'll never forget - when I sat in it for the first time it smelled exactly as I remembered. Still have it and am gradually refreshing & renewing. This year was new upholstery and over winter will be dash pad & door panels. 118K on the clock and the engine's a little tired. Someday I hope to address that too.
If you're missing that special car from years gone by, don't give up hope. You just never know.
