Whilst I agree with your thread, you are probably quoting the very cheapest unregistered Oceans with the most expensive used. You're right you'd have to be insane to pay £65k for a 3 year old Ocean, but there are some nearly new examples with low mileage for low 60's which in the current market is more realistic.
We all love our Cali's but some need a dose of the current economic reality we live in. There's still some nearly new 4m Oceans for sale for over £85k. I really feel sorry for the unsuspecting buyers who pay these crazy prices and lose £20k the minute they drive them away.
yes, I definitely am comparing the cheapest unregistered Oceans available with some of the vans that look most overpriced, but doesn't the general point hold? Here are the rest of the 6.1ks:
68k new, unregistered, 5 year warranty and service vs £64k, 2 year old van with 4000 miles and 3 year warranty
68k new (etc) vs £59.5k van that's 4 years old with over 25,000 miles, presumably no warranty
68k new (etc) vs £54k van that's 7 years old (204 and 4motion - though some (e.g. me) think that's worse not better), obvs no warranty
£68k new (etc) vs £63.5k van that's 2 years old, 10k miles, no mention of extended warranty
£68 new (etc) vs £66.5 van that's 3 years old, 18k miles, no mention of warranty. 204 4motion, but again not always a positive.
£68k new (etc) vs £62.5k van that's 4 years old, 28000 miles, no warranty
£68k new (etc.) vs £65k van that's 1 year old with 8500 miles, under 2 years warranty remaining
I think none of those look competitive on price, not even taking into account the fact most people much prefer to deal with a dealership when buying. To be clear, some of those vans are higher specced than the £68k new examples, but options depreciate very quickly, most buyers of used vans don't care about options aside from 'must haves' (e.g. Beach buyer definitely wants a heater, but Oceans are so well-specced there is probably no must-have). Also when one orders a brand new van, one pays extra for options because one is sort of creating one's perfect wee van. Used buyers tend not to be like that (again, except for things like the heater, 3-zone and LED lights on a Beach).
I suspect most or all of those used prices are flexible, certainly more than the new unreg van. But that's part of the problem. Nobody wants to drive for hours to view a private van and have an awkward conversation with a private seller about what they will really take for the van. Better to advertise the real (lower) price you'll take and make clear it's not up for discussion.
A few weeks back this topic came up and I refrained from saying anything about vans advertised here because it seemed a bit crass and unfriendly, but since this thread is specifically devoted to that topic, and the feedback could be useful to sellers, I'll be more frank now.
Another factor is that for some buyers financing is easier/cheaper with a new van, and when buying from a dealer. That's ultimately a price point though because it should drive down the price of used vans rather than new vans.
