not to sure about the PSI and shit. The SI batteries can be done yourself although i am not to fimilar with that, mine had already been rigged up when i got it.
Take the side panel off, under the back windows, and you'll get a good view of the wheel well, to see the condition. If it is rusty in there it is very hard to fix.
The CODE that you see on the stereo, is a security thing. When power is lost to the stereo, you have to enter the secturity code to get it to work again. If the guy you bought it off of, doesn not know then you can uasully find out from a dealership.
Usaully the eta's are pretty strong motors. The strongest the BMW made, and shouldn;t have to worry to much about the motor, as long as the reg things are kept up with.
if you havent bought it already, and don't end up buying it, mine is for sale and it is already done up, you just have to transport it across canada. hehehe
