I've seen many comments over the years about WBAC, Carwow and others - I've just completed my second transaction this morning so thought I'd post in case its of use for others - In general the process is slick and had no issues in either case. The carwow estimates were significantly higher than those of WBAC and there was no haggling on the handover day. Before: - Used the app in both cases. I think it would be a faff through the website, but on the app you can take photos inline as you're going through the process - You enter the reg and it gives you an estimated price. In both cases I received a fair bit more. - You have a guide/overlay for the mandatory photos, there are quite a few but its not excessive - this includes photos in and around the vehicle and from multiple angles, all 4 tyre closeups, the V5, service docs, odometer/dash and with additional asks for closeups of any declared damage (I had none) - There's a free text field to add any options/modifications - You can then save for later or open the sale where you set a reserve price if you want (I did) and pending approval it goes into auction the next working day. Both cars were in excellent condition and low mileage, which I assume affects the experience quite a bit. The sales: First sold a Porsche 911, I set the reserve around 12% above the estimated price (and a lot more than I had an offer for trade-in) - in this case the estimated price was wildly wrong. Porsches live and die on the options and I suspect the estimate was simply a book value that did not account for these. I had a call immediately from Carwow rep to confirm some details and then a follow up from a specialist vehicles team later that day. The character limit wasn't enough for the (extensive) options on mine and this person confirmed all of them and assured me they would be properly represented to dealers bidding on the car. It went in auction the next day and sold for 5% above my reserve price. I was happy with the price and whilst I'm sure there was a bit more in it if I were to sell privately, it wasn't enough to be worth the hassle. Next was a Nissan Navara - the estimated price was on the low-ish side but not totally out of order, and still 12% more than a trade-in valuation. I set the reserve at or close to the estimate, no additional calls after to confirm and just an email within 10 mins saying the listing had been approved and again it will go in auction the next day. It closed 7% higher than the reserve. After: Quite a different experience between the two of them. The Porsche was collected by a driver from the purchasing dealer - turned up, looked at the car for 10 seconds, turned it on, checked over the docs, called base and said "yep, tidy, pay the man". Money was in the account within 5 minutes. The driver was orchestrating a few car purchases/deliveries around the country, parked it up outside the front gate and came back later that evening to collect. The Navara was collected by a 3rd party agent - had a process in an app to run through that involved dozens of photos, a short test drive (I drove), and once he sent the photos to the dealer did a walkaround with them on the phone as well. A much more thorough handover than with the Porsche but in the end no issues, confirmed all was well and cash in the account before the driver left. General: I will almost certainly be using carwow in the future as a default option when changing cars - in both cases there was definitely enough in it to justify the additional effort, and I think even with a much lesser value it would have been too. I traded in a 2019 Mini Cooper S recently I'm sure doing it through carwow instead would have netted me at least another £1500 if not more still - but it is what it is. I found the process in both cases a little bit stressful, but that was more concern for the unknown - there was absolutely nothing that warranted it through the process but just thoughts of... what if it doesn't sell? What if they try to find reasons to mark it down? What if what if what if?
