No no, I am in Finland where E32 750iA:s can be had with civilized length (used from Germany). So it is the normal model, not Lang. I was under the impression, that the mechanics under 750iA and 750iAL were the same, just that latter has 25cm more length on its body?
Anyhow, just found out that about the H31 (or something like that) hydraulic system. Yes, now I would like to change the brake servo from hydraulic to a normal vacuum-operated - the brake feel is told to be better.
