I believe a Prius is better than a full gasoline engine. What do you think?
It is possible that the Prius will cost slightly more per mile in repair costs.  You should get that back in fuel savings. 
I agree, especially with gas prices rising. Do you have experience with the maintenance costs? 
I had a dealer quote me about $2500 to replace the battery. There are more parts on the hybrid, so more things can break, the battery is just one.
Thank you. This is my first Prius. Have you had a good experience with yours? Should I be worried about anything?
Within the 150,000 mile warranty it is all smiles.
Great. I am excited to drive more. Are Prius' good for long road trips?
It is a great car for road trips.  The best part of a road trip is you decide.  Fast or slow.  See what you want to see.
Thank you. I hope to plan a road trip in the Spring. Hopefully the mountains if there is enough horsepower to drive there
If you feel there is something wrong, like a loss of power, I suggest a mechanic for an inspection. There is risk if there is a problem.  Is it new, or just new to you?
