2008 E92 Lease/Selling/Trading options? [noob here]

Hey everyone. Been a while since I've been in here.

I love this car, but financially its not working out anymore.
My parents got it for me initially. For a 3 year lease.
Upon the return date, my miles were way below the term, and I definitely was looking to buy it because of the condition and such low miles.

The guys at Crevier and I punched some numbers and re leasing it again then buying it looked like the right move to go with. Which I did.
But as of late, I'm having trouble with the payments + insurance and all.

The dealer was dying to get the car back from me because of all the upgrades my parents had done + low miles obviously. And i dont think much has changed since a year ago.

I'm really terrible with this stuff, And i'm pretty sure I made the wrong move by re leasing. Can you guys please be detailed as to what options I have. and what you would do in my shoes?
Much appreciated.


Here's some specs about the car;

2008 335 Coupe/Manual/Saddle brown w/ Aluminum -- 39k miles
Fully loaded with Nav minus heated seats
Bmw upgraded body kit + upgraded rims
And the car was BMW certified when I re-leased.

Here are some pics of which body kit/rims i spoke of (The car literally is in the same condition, sorry for the non current pics)

Please let me know if you need current pics to help with any answers, Will take a few tomorrow morning if needed.

Cheers guys
