Today i went for a short road test with my 120y. I got some serious troubles in the steering, it seams that the 2 front wheels are pointing inside.

Ahh the ol' toe in. What I did for that until I got a shop to do the wheel alignment was to get a piece of string long enough to run around the car at axle height (or a little lower to clear the boywork), tie it off so that tight but not going to break when you adjust the toe. When you adjust the toe in\out you'll notice the string loosens in spots and you can use this to roughly gauge how much you've adjusted. Obviously then using a tape measure on the front and back of the tire can give you a better indication of how much toe you're running.

I also got electrical problems, the brake lights don`t work...

checked the bulbs and fuses? I thought the instrument lights were out once but it turned out it was the taillights too.
