I've seen many conversions done for $3000 (and some much less!). It's definitely doable depending on your goals. Home made adapter plate, creative solutions for a coupler, used fork lift motor, lower end Kelly/Alltrax controller, and Walmart batteries - you can do it.I'm a school teacher, so I don't have a huge budget for this. Any idea where I can get a REALLY cheap forklift to take parts from to start my conversion on a 1994 Saturn? I really want to do this, but it seems everyone spends $10,000 to make a conversion. Not bad for a new car, but money is one of the reasons I want to try a conversion, the other being fun of doing the job!
I'll let someone more experienced with fork lifts than I to suggest where to buy a motor. All I can think of is junk yards.
