its $40? If its going to break you then you have other problems.

For your ROomate, thats why i never live with anyone anymore. Cant depend on **** from anyone. Make sure he doesnt use that garage AT ALL if he isnt going to pay for it and hes going to back out.

As far as the civic goes,yeah it sucks, i drive one too, but the gas mileage makes it worth it. I get passed by S2000s, RSXs, Other nicer cars that prob get the same gas mileage, but you know what, its just an all around cheaper car to own. You are doing yourself a favor by driving it and use your bike to "go fast and clear your head"

Keep the civic, buy a $40 headgasket and swap it out when you get time, but make sure its a headgasket.

As far as the garage goes, if $40 is going to put a big strain on you then you need to look at your other financial statements because you got something else going on . $40 shouldnt be a matter of life or death so like someone else said cut some other stuff out to make up for it.

Go out 1 night instead of 2 a week, eat out less, etc
