On May 29, 2010, I had a Hymotion A123 plug in hybrid kit installed on my 2004 Prius by Smart Toyota in Madison, Wisconsin. Since that time I have been very dissatisfied with the kit. The function and use of the plug in hybrid was not fully explained to me. I have a degree in engineering and used to work for General Motors. I get what Smart is trying to tell me but honestly, the kit does not work. In all fairness, I must tell you they have offered to replace the kit at no charge. Here is the problem, even if the kit did work, I would like it removed from my car. I am not willing to drive the way it takes to fully appreciate the advantage of the plug in hybrid. Again, I was not told about the driving change I would need to make before I purchased the kit. Now, here is what I don't get. Smart Toyota says the kit can not be removed from the car and they have refused to remove the kit, even if I pay to do so. What gives with this? Can the kit be removed? I have phoned and emailed Hymotion and they have not contacted me either. Does a removed kit have any value on the open market? Can the car be sold for a fair price with the kit in it? If someone near Madison, Wisconsin, would like to take on the project I would sell them a Hymotion converted Prius cheap. It is a 2004 dark red metalic with 33k miles and loaded with everything but leather. It is flawless and has never been smoked in. Any suggestions? The car should be worth $12K to $13K and we all know the kit was over $10K. Any sincere help would be appreciated. Thx.
