^ That's a common problem for BMW's (E36, and E46's anyway). GM's even worse. After 3 years or so, you'll start seeing it.
OP is definitely a scammer.
There is no real Accredited "Electronics Eingineer" program. It's either Electrical Engineering or most likely a technology school... but not Engineering
These electronic rust boxes don't work. In theory, it' is great, but it doesn't really work.
Your best bet is some good rust proofing the day you pick up the car, and yearly or bi-yearly applications - or don't winter drive the car.
