Bought one around 3 years ago as well. $14.5k, enthusiast owned, had less thank 100k on the clock. I'd guess it's worth around $18k now. Matt is right, they are going up in value.
The retro-ness of the nav screen with a tape deck behind it is only going to get more charming as time goes on. You can still get up-to-date nav DVDs that will nav you around, no problem. If you don't like it you can just turn the screen off and it's like it's not even there.
The very subtle-aggressive styling and the fact that it had Servotronic Hydraulic Steering is what makes this car an easy classic.
