Hi all ,been a while since i have posted but still keep an eye on things

anyway here is my problem , RUST , well not so much me as my car

i have had my brillant red 4 dr se for about 9 years and most of the old skool guys will know the car , Ant ,Ian ,Ste ,Adam ,Sal etc etc it was in tbmw jan 04 and also at a santa pod meet in 03. anyway rust has finally caught up in all the usual places

and im not sure what to do with it ,its too expensive to repair so not sure if i should sell up complete and buy a nice standard car or maybe a cab ? or break it as best i can altough i still have to be able to move it coz of the position of my garage, and save the bits for another shell ? i dont have the room or funds to buy a donor car as i have just bought an 36 sport as daily transport . i had planned an m30 conversion and have most of the bits ready for it as well as a z3 short shift and big brake kit and i have added so much to the car over the years ,here is a quick rundown;
black sport leather ,mtech 2 wheel,illuminated mtech gearknob with leather gator,leather handbrake gator and grip ,ctr armrest ,obc,cruise ,illuminated mirror,rear shelf blind,eibach arbs, springs and strut brace , e36 m3 rack ,e36m3 rad and electric fan, hartge rims, chip ,bbtb,magnex exhaust, almost new bridgestone so3s, genuine lwr arms with offset bushes etc.
what would you do ? cheers paul.
