hpi help

hi all im trying to do a hpi check on a car and i cat get past the address stage . It keeps asking me for a postcode??? anyone any idea or has anyone used hpi checks online before?
any help would be great

any time i have got stuct at the postcode part i've always put in 90210. Althought it wasn't doing a hpi check. But it didn't make a difference to the final outcome

I use [SIZE=-1]SW1A 1AA.[/SIZE]

cheers folkes... car i was interested in has no service history so ive decided to walk away. On a seperate issue what is wrong with a vw bora. Ive been in the market for a tdigolf for a while and cant seem to get a low milage for the price im willing to pay or else i have been piped at the post by someone else who has bought it. Ive seen one or two boras that seem well resonable and they dont look as intimadating to drive as a passat

Bora is not a bad yoke. Unpopular in the UK so likely be cheaper too.
