2007 Audi S8 5.2l V10

I bought this about 2 years ago at auction. It was hit in the right front. No airbags deployed. I replaced the hood, headlight, bumper, passenger fender, and radiator support. I have registered and driven it since. It however is not perfect. The front bumper still has some damage repair from parts carried over from the original bumper (see photos). It needs a rear left brake caliper motor (parking brake light lit). It also has an oil leak I've been chasing since I bought it. I replaced the oil cooler and resealed the oil pan but it still leaks about a quart every 400-500 miles. Lastly, it has a suspension air leak in the rear right. I replaced the air shock with what was supposed to be a good used one but it still leaks. Takes about 4-5 hours to lose air, so you can drive it without overworking the air pump. Lastly, it needs a passenger side airbox. The one in it now works but is cracked. Everything works, runs and drives great, just needs some TLC.
Moving on to other projects, lost interest in this one.
