Yes depends on the car.
Many of the hybrids are an expensive cost but tax credits and offsets help with the initial sticker price. Some of the lesser expensive hybrids are made by Toyota and Volkswagen.
Hybrids perform better than gas cars. Most hybrids get at least 40 MPG (some get as much as 60 MPG) and are actually no more expensive to repair than a gas car. Seems worth it to me!
Yes the geothermal are expensive to fix because they have to use the same process of installing it at first
If it is within your budget. Just remember expensive cars are expensive to fix.
No. The mileage depends on the car, the more expensive they are the more options they have. Some more expensive ones do get better milage but you can opt for more milage and less money by giving up some extras.
Depends on what needs fixing...
No, according to http://www.autoevolution.com/news/how-diesel-electric-hybrids-work-and-why-they-aren-t-on-sale-yet-20472.html the reason why there are currently no diesel electric hybrids is because they are too expensive to make.
It depends on if it customized or not, if you want original parts then it shouldn't be too expensive. However if it is customized then it will be more expensive.
yeah
No more so than a Honda.
shift linkage needs adjustment, not expensive
Dodge Stealths were notorious for being expensive to fix. Many or most of the parts were specially made for the model.
