Try Contract Hire instead, no large deposit and no final payment.
Best deal I have come across recently was on a VW Transporter T32 102PS
£228 +VAT per month for 3 years.
3 months payment as deposit.
I had no large deposit.
3 months payments, then no payments for nearly 2 months.
Something fishy there Alex.
That only comes to 9600-odd, and a Transporter costs nearly double that.
My van is 276 per month and 5000 to pay in 4 years.
I'll change it after 3 years when I owe 7100.
Not a problem with a 3 year old van with 15-17,000 miles on.

It'll be worth closer to 8000
Trade it in for another new one, and off we go.
(sorry I've got no pound signs, but I installed a new Windows and it's set to US keyboard, and I don't know how to change it!)
