Assuming these are the last of the items to sort, you're going to quit with $1500 to go after sinking $6K in repairs?

The brakes are an easy DIY.

The engine rattle is probably a motor mount. Another DIY job.

You can pick up a compressor at OK Foreign or Porsche Dismantlers, install it yourself, and have someone clear and charge the system.

So many questions from your post. You bought the car knowing the AC wasn't working and now it's an issue? When you had the trans out for the clutch, why didn't you pop for the IMS? Did the car come with records?

It sounds like you bought a car that's been neglected for a while and needs some lovin to get it back up to snuff. You're probably not too far from the end of the tunnel. It would be a shame to sell it to someone else to enjoy. But wait for the response from Randall...
