Thanks for the responses all, even the character assassinations and GCSE psychology assessments…..
Texted him this morning and told him that my offer is fair and that if he had have had the car inspected and the fault came to light then I could have used my warranty and neither of us would be out of pocket so the responsibility lay with him. Offered him £650 as a goodwill gesture with no admission of liability but that is the limit. He phoned back an hour later, said the garage had told him a new cambelt by itself would cost £400, he appreciated my offer and would like to accept. We have agreed that I will pay the garage directly when the work has been done but I want to see photos of the car in pieces before I pay anything.
So there we are, let the cries of “you mug” etc recommence, I think it reflects worse on you than me. I do think I’ve been generous but I said I wouldn’t walk away in the event of a problem and my Dad always said you should be true to your word. Although he never bought us that windsurfer he promised us, the lying git.
@ Jamie – that’s three examples of compliments you gave me, I insist I pay you £30! PPG ok?
