Hi Ray.
interior kit for an avant is £34. in that you get: front and rear dome lights, front map lights, glove box, boot roof and boot door.
for the outside: £32 for ice white fogs, dipped and full beam, sidelight kit is £12 which gets you the 5 led bulb and canceller looms.
Cant do the numberplate lights just yet on a B7, you will have to wait until March.
I will cover the postage on all the above if you want to go ahead with it which will be postage to the UK.
For the B7 retro fit the prices are as follows.
for the OE lamps unless you can raid a breakers yard for them as they are the expensive part for the retro fit, for 8 white lights (4 puddle, 4 footwell) and 4 red are £130 which are from Audi with my trader discount.
door looms are £12 each and footwell loom is £20.
LED's to go in each lamp is £35 for the 6 pairs of panel lights that fit in there.
If you don't want the footwell lights then minus £40 which are for the 4 lamps for the footwells.
