If I were to get $10K and had cars that were getting up in years? I would trade them in and get newer cars.
While a vacation is nice...it's time and money....so i would consider a nice weekend get away...for example - to Williamsburg, VA - Great Wolf Lodge - and get a GREAT room.
You might be ale to find a leather couch on sale - especially with the amount of furniture stores going out of business? Yeah...we got our 3 piece black leather for less than $3,500 - couch with two recliners, love seat with both positions reclining and a single recliner...all leather....brand new...
A camera? if you use a camera regularly - yeah....
In the long run? I would do the "material" things - like the newer cars and do a get-away instead of vacation...
I'm sorry for your loss. I pray your aunt's memory is eternal.
Enjoy the inheritance...make sure there aren't any taxes due on it. You don't want that surprise...
Good luck!
