I could be wrong, but I think all the retrofitting is because they are so unreliable in the first place. Of course you can't use a Prius to push a damaged 3/4 ton pickup out of an intersection, so certain capabilities would be lacking (although usually they just call a tow truck anyway) but in terms of wear and tear and required maintenance from just driving, especially with 12 hrs days, I bet statistics would show a stock Prius beating out a refitted CV any day. Any data to support your contention they aren't up to it? Remember the favored vehicle of the Taliban? Small toyota pickups. Nothing got harder duty than that. I'm sure they didn't do thousands of dollars of retrofitting either.

I waas giving you the perceptions of the cabby and what he understood the position of the cab companies to be. Bear in mind that some of them get used cars at say $3,000 and refurbish and sell to the cabbies at $5,000 - not much room in there for a Prius yet. (His story and numbers not mine).

Absolutely - I wasn't taking what you wrote in this regard as your positon. I was just sad to see that the old perceptions remain so pervasive. Certainly the issue of initial cost would be real, even if reliability is not.
