Be interesting to see what they advertise it for
£49,900 is what it sold for by the dealer using their sale or return service. Their commission on the sale price is £1500 + VAT and I think they said its £150 + VAT for any preparation work required on the car, so effectively the OP will have pocketed around £48k.
After speaking to the same dealer, I’ve been told I can expect the same for mine as the spec is not far off to that of the OP and well below average miles. However, I’ve quickly ruled out selling my car by such method, to do so you have to be brave (nicest way to put it) and keep your fingers crossed that nothing happens to the company and you get paid. Also, in the contract between you and the dealer, it states that you need to inform your insurance company of the cars new location and in the event of a claim for any reason, you have to claim on your own insurance. Now imagine the dealer takes a potential buyer on a test drive and has an accident, they will have third party insurance but your own car isn’t covered and no private car insurance would cover you in such circumstance, especially with you not being present and regardless if you’ve updated where the car will be kept. It would not be limited to just that situation but any other you could conceive when giving custody of your car to a third party.
There is a mountain of horror stories reported by people on various forums using sale or return to sell their cars (NOT by the aforementioned dealer) and although it has all worked out well for the OP and no doubt many others, I personally don’t think the risks are worth taking.
I’ve instead contacted some specialist dealers for a straightforward cash sale, most have given ballpark figures subject to an inspection, but the values are promising!
