Hi.
Looking at trading in my Mk5 for a Mk6 on order. Dealer trade in was 700 less than the price from we buy any car. A broker also added that they were actually ok, BUT you have to be very very honest regarding the car conditon and during the initial quote ensure you include every single little scratch etc as when they view the car, they will try to get the price down. After all they are a business and if you go to them odds on you're after a quick sale so they will use that (i.e we have cash waiting), but will want to get the best price possible in order to max their profit margin \ overheads etc.
If you think about a price similar to the trade in value then you've got a good estimate it seems.
I'm going to use them as a fall back option = private sale in Feb maybe (but a little worried about people coming over to the house \ test driving (i.e have they insurance for the car if it's crashed - prob not!), then it's a case of dealer vs webuyanycar and see who gives me the best price.
if it's only about a grand or so, will just go with the easy option.
