The one thing I have learnt from Ebay is never when selling to leave feeback until it is left for you.

In this case i would be very reluctant to refund any monies for any goods returned

Is there any way you can garentee that its the turbo you sold that you get back???

he could clearly see from a pick what he was buying.....

My advice to you would be to send a very nice email saying that It would be cheaper and easier for him to put it on Ebay and sell it for himself he might even make some extra cash

Worth a go...I did this and it worked
