Just purchased a 2010 Accent. Could use some insight.
 

Any common issues with this model I should be aware of and if so, any preventable measures I should take? I was also wondering if I should take specific care of the car. I have only owned a 87' prelude and it had a few issues so I was at a shop about every other month and I want to avoid that since I don't have huge amounts to continuously spend on repairs.

Also, personalization: any interior/exterior mods I could purchase to make it my own personal accent? If so some trustworthy links would be greatly appreciated!

And my last question! Any way to get some more HP or faster acceleration out of it? Today (the first full day I've owned it) I was going onto the interstate and it switched from 25 MPH to 55 MPH and it seemed like it to a little bit to get kicking compared to two other cars behind me. If someone has some information on that I'd appreciate it as well!

Thank you for any help in advance!
