Hi.
I actually bought the 2003 seats. Put in the back seat that just fits without problems - untill my daughter should fasten the seat belts. The Seatbelts from older version does not fit in the lock of the newer version. I do not have older seatbelts and instead tried to change the seatbelt-locks. But that is impossible. The bolt is hidden behind a metalbar.
And then I tried to find out what problems the front seats would give me. And then I gave up. It is not possible for the reason of the seatbelts.
I am now in the midst of selling the 2003 leather seats. And have bought 2006 leatherseats instead.
Best regards
Richardt
