A6 Avant & seat retrofit Help Needed

[pwack]

Hello All
Looking at getting back into the A6 fold with an avant 7 seater but i need to either find one with the 2 rear seats already in or buy an avant and retrofit the 2 seats.

Picture the scene-christmas exe,putting the four kids and the wife into the sedona to go to the inlaws in nottingham and turn the key and nothing happens,transponder ariel that picks up the transponder in the key for the immobilizer packed in,cant start the car ,nowhere open for parts,we were stranded.

My Vel Satis is a big car but you cant fit 6 people in it so we decide i need to get a car that has the option of 7 seats if we needed. it.

Im struggling to find an A6 with the seats already in so im wondering has anyone retrofitted the extra 2 rear seats before,if so how hard was it and how expensive was it.

Also
Is any one selling a nice petrol A6 avant with 7 seats(with under 100k on the clock)
or would be willing to sell the 2 rear seats if someone has them but doesnt use them.

Thanks
Pwack

so long as you have a later model (post 2000 I think) then you can retro fit, but if you can find the parts, they'll be expensive (I think it's about £1500 for the bench seat and seatbelts)
