Where does the oil leak come from?

I have a 04 ford mustang. I knew my car was leaking, but I wasn't that worried. Yesterday I went to a 3 hours trip, one way of course. When I got to my destination, I saw smoke coming out of one side of my car. It was just a little that I couldn't find the source. Today in the morning, I turn the engine on and notice the oil gauge was at it very Low. I checked the oil level and it was good. Then, I drove back home. Once I was here, I checked for any leaks. Thus I notice the oil pressure sensor was leaking. Then I checked below and saw other part that seems to be leaking. Which made me wonder if both are leaking or just the oil sensor. Here are some pictures.

What is average cost for front brake replacement on 2000 Mustang (in Oregon)?

I'm looking at trading my 1998 Dodge Neon for a 2000 Ford Mustang. This is in Medford, Oregon. They say this Mustang needs new rotors and pads. About how much would it cost to do a brake job on this car, at independent shop?

Added (1). Also, this is just a Mustang. Not a GT or Cobra. Auto trans and appears to be all stock.

2007 Jeep Wrangler or 2012-2014 Ford Mustang?

Alright, so I'm 18 and I'm searching for my second car. I took home a 2007 Jeep Wrangler yesterday from the used car dealership, but we haven't bought it yet, we're just testing it for now. It is burgundy, with no body damages, great interior, MANUAL (I haven't driven a manual before until yesterday when I practiced changing gears), and it has no problems. Also, 50,000 miles. The car is being sold for 16,500. On the other hand, I can buy an automatic mustang for around 20,000 on autotrader which has around the same miles. And is practically new. Which would be a better investment? Thanks ~ 2007 Jeep Wrangler or 2012-2014 Ford Mustang - 1

What causes a car to jump in reverse when all forward gears are fine?

I once owned a 1967 Ford Mustang (sure wish I still had it!) with a 289 ci w/2 bbl and factory 3 speed on the floor. I bought it used with 100k miles. It acted fine in forward gears but when I put it in reverse, It "jumped" as long as I was moving. I changed out the clutch and pressure plate twice but it didn't help. Could it have been that the fly wheel needed balancing (by grinding) or something else?
