    Here's the machine's specs...

    Model Name: MacBook Pro
    Model Identifier: MacBookPro5,3
    Processor Name: Intel Core 2 Duo
    Processor Speed: 2.8 GHz
    Number Of Processors: 1
    Total Number Of Cores: 2
    L2 Cache: 6 MB
    Memory: 4 GB
    Bus Speed: 1.07 GHz

    We thought for surre that my wife's MBP was on snow leopard, but alas. Any help would be appreciated as we are both really excited about the new features in mountain lion!

    As long as the computer meets the mountain lion speq requirements, you should be able to just buy mountain lion and upgrade.

    This needs snow leopard.
    The OP is an OS behind.

    You will need a dual layer DVD or an 8 gb USB drive. Since their is no way to upgrade from Leopard to ML you will need to do a clean install. You will need to backup your data.

    Try going to an apple store. Then ask them if you could download a copy of ML on one of their machines. Then create a bootable USB drive. Instructions here. Then clean install ML.

    Thanks for the help guys

    I'm willing to pay for snow leopard or lion first to get to it, but they've taken them both out of the store. Do I need to find a hard copy of one of those first, or is there a paid/legal downloadable version elsewhere on the web?

    You might be able to boot into Lion recovery from a thumb drive using this method....

    Download Lion from the Internet, you will have to buy it though.

    Genius Bar should resolve for you if you buy ML, etc.
