2007 Dodge Caliber R/T

You should do a full inspection of the front and rear suspension. If your rear subframe is rusted through, your front subframe might also be rusty and headed toward a rust driven failure. Also, various suspension components might also be rusting out and need to be replaced.

It is unlikely that the only component that needs to be replaced is the subframe. You need to get a picture of the total cost of repair for the full front an rear suspension.

Then you have to balance that repair cost vs the value and longevity of the car. Dodge Calibers are not particularly reliable and at 275k miles, your car is very near the end of its service life.

Now is not the time to dump a bunch of money into it.

Thank you for the response. I have checked the front sub frame. There are a few spots that have rust. I looked at the cost. The cost is a lot more than the blue book value. I was thinking about putting it on yahoo marketplace as a parts car. I would like to at least get the cost of the tires out of it.
