I agree with both answers here, I had to have my Golf's wiring harness done twice (first garage were a bunch of idiots) but I loved driving that car..

As to the knee, do not accept! Just keep doing all the PT exercises and don't get discouraged.
My ankle (broken in 6 places - twice each bone) is far better then anyone expected because I just kept at the PT. It's about 98% and I was projected to get about 85% back with muscle pain and weakness.

Good luck w/both issues.

And you have my sympathy with the sick boy.
