I picked mine up from a junkyard for $50, while I was swapping a rack and pinion and motor mounts, so I decided why not.
The GA brakes were a matter of getting new calipers and some R1 concept rotors, but I was going to replace those anyways, in total it ran about $300 with EBC Yellow pads.
For being comfy, that's why I kept the A/C, Heater Core, blower motor, heated seats, stereo and wipers defrost etc. Not going to lie it's a little bit noisier on the inside but probably the equivalent to driving a S-10 or Ranger around which doesn't bother me or my dog at all since most of the time the windows are down anyways.
