Broken heart

Pull the trans, open the rearend. Fix what's broke.

Easy.

My heartfelt apologies on this mishap.

If I lived near you I'd let him drive my race car to prom.

Me and my pops build cars together and it's a great thing. As bad as it seems now, you're both still alive and will rebuild the car and many more.

Edit. This makes me mis my grandpa. He could fix anything.
