Well... maybe the photos look over dramatic. A good cut and polish, she'll be like new...
Really.
Mines - at the end of the day, what you do to your car is your business... but take any discussion of 'repairing to sell' that vehicle off this forum.
It is: 1: Illegal, 2: Dangerous, 3: Expensive.
No-one here will condone that type of activity. You can easily buy a front-cut, but that is to use for part (engine, loom etc), not to weld onto the back of another car.
Please - for the sake of humanity - sell the parts.
Stop any thoughts you have about repairing it. You'll actually be better off (financially) by selling the parts.
If you do come to your senses and 'wreck' the car for bits - I'm serious about your boot-trim bits... but need to see them first.
This is all I will say on this topic.
