Can I upgrade to Mountain Lion and to Mavericks?

Question

I never upgraded any further than Snow Leopard because I thought my MacBook Pro couldn't, I'm now thinking I made a mistake.  I have been reading some of the posts on here and it seems that if the Mac is mid/late 2007 it can be upgraded.  I have found out through my serial number that it was made in March 2007 obviously bought a little later than that but it is boarder line on the recommendation.  These are the specs for the macbook, if anyone can put my mind at ease it would be helpful, i just need to know if upgrading is really worth my while.  I run an imac and it's completely up to date so I know what I'm missing.

No. You need the same requirements for Mountain Lion as for Yosemite. You need a model identifier of 3,1 or later.
Upgrading to Mountain Lion
To upgrade to Mountain Lion you must have Snow Leopard 10.6.8 or Lion installed. Purchase a redemption code at the Online Apple Store: OS X Mountain Lion. Mountain Lion is $19.99 plus tax. Use the code to redeem a download of Mountain Lion from the App Store. The file is quite large, over 4 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
     OS X Mountain Lion - System Requirements
       Macs that can be upgraded to OS X Mountain Lion
         1. iMac (Mid 2007 or newer) - Model Identifier 7,1 or later.
