Unfortunately none have tow bars, the Transit doesn't and has no MOT or Tax, so that can't be used, otherise that would be an ideal vehicle really to use. I think my only course is to give him a full refund, and just get the vehicle back to me. I'm really hoping it's something simple and it can be fixed. He did say he wants to keep the car if I can fix it, but he's giving me about 48 hours to get it done. He has another car, so it's not like his stuck. I understand he's not pleased, I'm not sure how to play it. I want to try and do everything as much as he wants, but I don't see how I can.
If he is being funny and demanding a repair within 48 hours then don't take it back. Whats to say he hasn't thought I don't like this and ragged it like a gooden and done the damage himself? If he was resonable then yes, I understand what you would like to do, fix it etc I would do the same. On the same token if he was being rude which is how it comes across as you're not legally obliged to do anything I'd tell him to piss off.
I think that's about where my thoughts were leading at the end of my reply. 
If you go in with guns blazing ranting and raving and throwing your teddies out of the pram before trying to amicably sort out a problem you rarely get the outcome you want in life.

Josh - to echo my PM, I agree with Kevin.
As I said earlier, a resolution is either on your terms, or not at all.
At the end of the day, if you said to a small claims court:
"I offered him a full refund or a suitable repair within 2 weeks, but he refused becuase I couldn't do it in 48 hours"...
... they will take the view that you have made every effort, and I will imagine the outcome being in your favour

With all respect, it's an old Omega for a grand or two - not a 20k Rangie or simelar...
All in perspective Josh.. don't lose sleep - give me a ring, as per the PM
