I copied this from the Chicago RTLO which is attached to the CAR lease:-Before a landlord can deduct expenses for damages from the security deposit, the landlord must provide the tenant with an itemized statement of the damages within 30 days of the date the tenant vacates the dwelling unit.

Cars shouldn’t be leaking oil.

But even if they didn't I'd probably put it in there anyway because, as Carly Simon said, I'm so vain 😄 

My hubby just got a job, and so our 1 car is in use every day.

Please disregard the bad grammatics I'm in my car dictating through this on Android auto so some of it's coming out kind of garbled I'm sorry but I think you got my point

Here in the Pacific Northwest any exterior (stairs) wood  rots quickly, so I choose to put my stairways inside.  1000sf for cars, 1000 sf on top, three rooms and full bath.

I’ll be moving to Fairfield county and commuting to my day job in NYC.From central ct originally so would like to be closer to home..a garage and car would also be nice ;)

Not unreasonable to ask them to cut it down IMO.I would sue private nuisance and injunction from maintaining a private nuisance, and for interfering with prospective economic advantage (scaring away potential tenants with prospect of dwelling and car damage).Start with a nasty-gram from lawyer since you already asked and was turned down. 

It is like selecting a car, they all basically do the same thing, some have more bells and whistles than others, but will you use all those bells and whistles or are you just looking to get from point A to point B.

You need a car and gas and insurance.
