Some questions about buying a used 2012 Accent GS
 

Hi All,

So I've decided that it is a good fit for me and started hunting for a used one.
I have a few questions though, and would love to get your help:

1. in the Hatchback GS 2012 Model - there are cruse control buttons on the right side of the wheel. Is it possible go install bluetooth and volume controls assuming I can get the head unit that has bluetooth, the buttons and the mic? the main question here is - does this model pre-wired inside the dashboard for that? I am located in the US if that matters.

2. Accent's with about 50K miles on them, assuming oil changes were made about every 6K miles - should they still be reliable? is there special things I need to inspect before buying an Accent with that mileage?

3. If the owner is missing 1 oil change record, and that breaks the 7.5K mileage interval for oil changes - how probable it is that if a mechanical issue with the power train will arise - the dealer will not respect the warranty?:confused:

Thanks! :)
