Quick macbook question

Hi i am purchasing a macbook from a friend. Here is my question he tells me that he purchased the computer in early Feb 08. He describes the tech specs as follows.
white macbook
2.2 core 2 duo
1gb memory
80g hardrive.

My question is shouldnt a the computer have a 120g hardrive if the processor speed is 2.2ghz Im hesitant to purchase the computer because their is a 2.0 ghz model with an 80g HD. Is their a macbook with a 2.2 and 80g hd???????

Even though he purchased it in Feb 08, he could have purchased the late 2007 model. Get a model number and serial number first before you buy. That would be the only way to tell exactly.

Regards.
