I get the occasional flyer from a Fiat main dealer who was having a promotion (close to end of year - get rid of demonstrators etc) on commercials. I went in out of curiosity, but said the prices were too dear.
In the yard was a year-old Scudo trade-in from someone who had got the next size up. I don't know how much he originally paid, or got as part exchange, but I paid just over half the price of new. I know nobody actually pays list price, but . . . I'd been looking through AdTrader, AutoTrader vans, a local firm who do fleet buy-backs, but this was the best value and condition.
Apart from the fact that the previous owner was a landscape gardener and it stunk of manure for a while

If you own your own home, and can borrow against it with no early redemption penalties, it'll be cheaper borrowing against that and paying as much off as soon as possible instead of going theough a finance deal.
Hope this helps.
Added later . . .An even cheaper deal
get a credit card with 0% for first 12 mths, buy your system with it, pay it off WITHIN 12 months and thats a bargain! buy now, no interest, thats what i'm doing now as i need to buy a new carbon pole. just remember to cut the card up after 12 mths.

But get another 0% card lined up in plenty time to transfer if you haven't fully repaid when the year's up
