about 2013 128i, is this a good deal?

so i've been doing some online shopping recently as I am going to get a new car soon
quite honestly, bmw is not my first option because i'm a student and my family hates the idea of me (student) driving a bimmer.
however i am thrilled when i came across this 2013 128i w/ SULEV that is selling for almost $30,000.
The car is basically stock, with only heated front seats, BMW Assist, and Satellite Radio.

what really made me consider this car is its 4 yr/ 50,000 miles free maintenance (or BMW has it already but i didn't know)

my questions are:
1. since the bmwusa does not say what standard equipment and optional equipment are, is connectdrive standard?
2. this car is not equipped with HID and angel eyes, is there anyway I could replace that in the future if i decide to get this car? or is it not recommended?
3. is this a good buy?

so far those are the questions i have. ill update as i come across more questions.
i'm fairly new to BMW world, so excuse me if i ask some questions that are way too easy or too obvious.

thanks!
