Long story short here...

• Contacted a trader on here asking if he had any engines for sale
• He replied and gave me a price and a mileage
• Sale was agreed and delivery agreed for about 2 weeks time on Friday 21st May
• Money was paid by Paypal and everything was fine
• Friday 21st came, I waited in all day - no delivery
• Sent e-mail asking why delivery hadn't happened and could I have tracking number and courier company details?
• Reply was that the engine was in a "Central Hub" in Birmingham because it had leaked "hazardous fluids". Seller promised to sort it out ASAP.
• No delivery or tracking information on the Saturday or Monday so I opened a Paypal dispute.
• Seller complained saying his Paypal account was his business bank account and he couldn't trade until I closed the dispute.
• I replied that i'd close the dispute when the engine was delivered...
• Finally on Thursday I get sent a tracking number very late in the evening saying the engine would be delivered on the Friday.
• Engine turns up on Friday 28th (a week later than it was meant to be delivered!)
• I observe a number of damaged bits on the engine - cracked cambelt cover, damaged pipe on the power steering pump, lug broken off the inlet manifold and replaced with a self tapper etc. - as well as there being a pattern alternator and a lot of surface corrosion on the block and dipstick - all indicative of high mileage.
• I contact seller to express my concerns and ask for confirmation of mileage.
• Seller comes back and states a mileage higher than the one given in the original email and blames the courier for the damage.
• I say that i'll keep it if he gives me a partial refund which he agrees to.
• He tells me I need to close the dispute so that he can use his Paypal account to issue me the partial refund.
• I closed the Paypal dispute early Friday evening and as yet haven't received the refund despite sending 2 reminder e-mails...
• When I checked all the courier paperwork there was nothing to suggest the engine had been sent any earlier than Thursday 27th...

Now, as you can imagine, this has not been a particularly great experience with a trader on here...

How long do you think is an acceptable period of time to wait for this partial refund before naming and shaming?
