Well my mate had 3 options..
1. Refund the total amount and take the car back with gearbox gone.
2. Have the buyer go to a BMW main dealer and have the car fixed and my mate foot the bill.
3. Try come to some arragement and work with buyer, 2nd hand box, non main dealer labour, half the cost etc etc.
In some ways my mate was unfortunate, but in some ways he was lucky as the guy that bought it was happy to go with the half the cost, 2nd hand box option...
The big problem is, Its a soft handed Judge that will make the decision, someone who knows nothing about cars. So its 50/50 at the best, if not more in favour of the buyer.
When its in court, a buyer saying that the seller got him to sign a Sold as Seen piece of paper, and then car blew up and when he contacted the seller he was told to fuk off, is only going to rise a judges suspicion that there was a known problem with the car.
As i said it is 50/50 at best, and judge could rule that there is no comeback, BUT they could rule full refund, or worse again, pay a main dealer to fix the problem.
Thats why my mate after being to his own soliciter, weighed up his options, and decided coming to some arrangement and pay half which i think was around 700euro was better than the possible alternatives.
As i said i am not saying its great, i can see where you could get fooked over as a seller, but also i can see where it may be needed by some buyers that have been rightly done by con men.
If someone sold you a car private and told you they owned it for 2 yrs and it turned out they owned it for 2 months, legally thats enough to get a refund!!!!!!, as its selling under false pretences, and it will be viewd that you wouldnt have bought the car if you had of known the truth.
