So I sold my 1992 Camaro and picked up an 89 240sx. I got it for $1000 and feel as if it was a excellent deal. Sold my Camaro for $1000 with 206k miles, this 240sx has 139k. My dad, on the other hands, does not agree with me. I have done some work on it already. The drivers window regulator was broken, so I picked one up for 60. The steering wheel is also off center, its a little to the right, but it does drive straight, I do not know how to fix it

... The weatherstripping on the drivers door was ripped, so I picked that up for 15. The exhaust was dragging low, so I removed everything from the headers down (including cat) and put a 2.5 inch piping with a 3a racing muffler, costing about 150 with installation and muffler. I do not have a passenger seat, which is fine because I want to install racing seats, did not come with a radio but picked one up from a friend for 35. I also want to pick up 4 alpine type-r speakers and install them on a 400 watt amp. Also had no hood hinges so I got 2 new ones for 75. Also, the key I have for the car does not work with any of the locks, trunk, drivers or passenger door. I don't know if they're stuck or just not the right key. The frame under the car is pretty rusty, I don't know if I should get it fix or just save up for a different project car. My drivers seatbelt is also, I think, off track. I can move it back and forth with my hand. It doesn't do it automatically as it is suppose to.
Here are some pictures, tell me what you think and some ideas on what I should do. My friend said the first thing I should do is cold air intake, haha. I will also upload some more pictures later, when my laptop isn't about to die.

My car getting the exhaust work done

Here is what the muffler looks like! It sounds good as well

Personally.. I want to get it painted a midnight blue

My girlfriend took advantage to the no passenger seat.

Heres the engine bay, somewhere on the drivers side I'm leaking power steering

Could someone tell me what this is suppose to be...

Powering 2 6x9s currently.. That will change when I get my new speakers.
I'll take some more pictures and upload after class
