Context: This is in Germany. It has to be Legal or atleast safe enough so that police cant shutdown my car because of the seats.

I have an E46 330ci which looks and drives very nice. I use it basically only for weekend drives in the summer. My only issue right now are the seats. It has the standard cloth "lounge chairs" which offer no support at all which makes spirited driving pretty difficult.

I dont want to buy recaros for 3k€.

Now I think there are following options:

1. Find some original E46 M Seats in good condition with electrics and heating -> I guess this is basically impossible or incredible expensive.(if anyone knows where I can find something in europe I would be glad)
2. Find worn out e46 m seats and replace the leather/cloth by a shop. Is that economic?
3. By a 3. Party seat by someone like Sparco or OMP. How will that work with TUV?
4. BUY E85 z4 seats. Supposedly they are plug&play. Will these get me through TUV?
5. Give my seats to a shop to modify? Is that even possible?

I would be glad if anyone could point me in the right direction.
