$1400 in batteries...hmmm. 120V is probably high, most work in the 48-84V range from what I've read..no matter. I don't think 20-3Ah is enough to get the car very far. Honestly, without knowing the motor draw, mass of the car, there is no easy way to shoot in the dark. I know a bicycle can use 3 of those in parallel and have a 20mile range at about 18-22mph, but that's 200lbs, not 2000lbs. So maybe taking that simple math, say 40 miles, upto 40mph? I have no real idea. Just firing blanks.
