Picked up an ET4 about 5 weeks ago with 11k miles that wasn't starting, had some body damage, and had been sitting in a garage for 2+ years. I picked it up for only $500. Spent a lot of time looking through the forums (thanks JIMC, you ROCK!) and after tracing wires, checking the meter, replacing the spark plug, replacing the relays, etc. finally managed to get it running.
The attached pic was from early on.
