Nope, you're not alone - $2500 is pretty high. That might be fair for a near-collector-quality game, but it's more than I'd ever pay for a Taxi.
...but if you want a nice-looking Taxi that plays well, you can probably get one for approximately half of that asking price.
Quoted from MNpinballplayer:
No .. The right taxi is worth 2500. Look at my taxi
Yours is very nice, and I mean no disrespect by this, but I find it hard to picture that Taxi selling for $2500. It looks like there may be some yellowing in the areas not under mylar (look at the bottom of the playfield, and in front of the left ramp.) There's minor wear by rollovers above the pop bumpers. Also, when I first went through the pictures, I thought I saw a slight bit of planking visible.
