I have a cableless tach that works. I guess that makes mine worth $7500 with my less than 80,000 mile 1.8L, moonroof, 5-speed and performance muffler. I'll even deduct for a needed wash and wax. And I only paid $180 for it, deal or no deal.The car has only 68,464 miles on it. I have never had to spend a single dime on the car other than what I paid to add the GT appearance package, tires, and routine maintenance.
I will disclose that the tachometer has not always worked properly. The needle only works about 20% of the time. I believe that this could be a problem with the cable.
