Since I am back, my car warms up very s.l.o.w.l.y. and doesn't produce much heat inside.
I've came to the conclusion that its the thermostat... where is it?... 'cuz I am planning to go get it myself anyways... I just need to be refreshed in E30 anatomy I think
ps-btw, my mecano made a mistake ordering my parts for my cylinders and struts: he ordered parts of 6 cylinder.. but its fun now driving on these speed bumps and I can steer with one finger hehehe...
