1st Gen Insight. My 5 mile commute in this weather is netting me 67.2 MPG, which would be MUCH better if I didn't have to go from 0 to 60 once, then back to 0, or if my engine could actually warm to temperature. Paid 3k for it, not too hard to find. I have a friend who is waiting to get one, and I pretty consistently send him links from here:

For me (with modifications) it is near impossible to get UNDER 50 mpg. Even with 30~psi in the tires, and cycling the battery and completely abusing it, I netted 54 lol
