Thank you all for replying.
Yeah, I know, Magento is one of the most popular and most used shopping cart solutions out there. I've also used it on a website I developed in the past. While it is, indeed, very powerful, Magento is also very hard to work with.
For the auto parts website I am aiming to use a solution that is easier to work with considering there will be A LOT of data. Thank you for the OpenCart suggestion, will seriously take it under consideration!
Any other opinions guys ?
