The issue, the way I see it presently is new orders are 14-16 weeks away, or longer for some specifications, so second hand are the only option if you can't wait. The delay waiting for the new, and off the back of the van sale boom last year has held prices strong!
The right specification stock is fetching big money, and with the price of the new T6.1 ever increasing, coupled with its popularity, and families switching to transporters as their family car, and I can't see it budging much in the future, at least not this year I don't think.
CAP prices are stronger than ever, although maybe slightly too strong in some cases, but see next few months and CAP values will be interesting. The big fleet sell off this, and almost control the market - 6 month old vans we were buying last year, have increased by approximately 20%+ in the trade.
Be an interesting few months for sure, as we are heading into the busiest period, with the end of the financial year for most business, holiday(UK based) season is just around the corner, and lots fo people with nothing to spend their money on!
