At this price point, cash is most certainly not king in my experience; we ordered our new CaliO a few weeks ago, initially as a "cash buyer"; however, after discussing it in detail with the dealer we went for the PCP option because doing this we got an extra £1000 deposit contribution over and above the discount we'd already negotiated plus we got a much better service package which is only available if you take the PCP deal (we got a discount of around 6.8% based on the OTR price).
They can afford to offer additional incentives when opting for PCP (or other finance models) because by and large most people who go that route will pay the monthly payments which include the interest; so both VW and the dealers want you to sign up for finance rather than buy outright; all the "extras" you get when going the PCP route are paid for by all the folks who continue the finance until the end of the finance term.
For us, we will settle the PCP within the first month of taking delivery so we will have a little interest to pay plus the £10 "right to buy" fee but overall we will have got a much better deal. I researched settling a PCP agreement early and as far as the VW PCP deal goes, there are no "early settlement" fees beyond the small amount of interest that will have accrued between the date the finance agreement began and the settlement date.
Our dealer said that in the end, most of "his" cash buyers end up doing it this way.
BTW - the maximum deposit you can put on a Cali on PCP is 30% (so you might have enough put aside before June '19); also, the production schedule for MY19 will be worked out by VW in August, with orders being fulfilled in anything from 2 to 6 months; so if 2019 is similar to 2018 in terms of VW's manufacturing schedule and you don't order until June 2019 then there is a possibility that you won't see your shiny new Cali until 2020 and so I'd consider following the advice of Verity above and order sooner; remember the only thing you pay at the time of order is a £1000 deposit (or £2000 depending on if you include any "dealer" options).
As for the spec, you are quite right in that the Ocean is very well spec'd as standard; although there are plenty of additional options available if you want them. Our local dealer was very helpful and knowledgeable but I've found these forums to be a far better source of info regarding which options to consider; the dealers tend to just say "yeah, great, I can add that for you" whereas on here you will find real-world opinion based on what people actually use; although for every "
good choice, get it" comment you find, you'll likely find equally as many "
don't bother" comments but the great thing is you get to see things from both sides of the fence.
My advice would be to spend time in the online configurator and for each option you want that you are unsure about, do a quick search on here and see what all these good folks have to say about it and repeat until you settle on the spec that you are happy with; then get down to the dealer to work out the best possible deal
Oh and one last thing, the extended warranty VW offer is an absolute bargain but you can only add it within months 1 to 3 of ownership (I think); if you wait any longer then you can't get it.
Welcome and happy CaliO shopping
