For example, I went to buy Jeep. 4xe version was $8000 more. But its battery lasts only 2-3 miles and it would have taken forever to breakeven. But dealership kept insisting that I will get $6000 in tax rebate/deductions so the actual cost is only $2000 more.
They had marked up the car by how much government was going to give rebate on and there was no savings for a taxpayer. I tried to have them issue give me discount now and claim my car on their taxes but, of course, that was not going to work. I ended up buying a cheaper model.
EDIT: Just checked the range, it is actually 21 miles on battery, which would have been enough for my usage. At that time, salesperson informed me that it was 3 miles or so. At 21 miles per charge, I may have bought 4xe. Math still doesn't workout, since I work from home I probably fill the gas tank once every 2-3 months. About $200-300 per year for gas. So it would have taken 7-10 years to breakeven after rebates.
