Absolutely nothing. Other than routine maintenance, I have had zero problems with this vehicle.
Rock solid reliable. I purchased my 2000 ZX2 in 2003 with 55,000 miles on it. As of 4/2007 I have yet to have any problems with this vehicle. Other than routine maintenance, I have not had to replace any parts or have any work done on this vehicle.
There is not much room, but then again I bought this vehicle knowing it was an economy car.
My ZX2 gets good gas mileage, it averages about 30 MPG in the city and 34 on the highway.
For an inexpensive economy car, it has plenty of power.
I would highly recommend this vehicle.
Having driven a number of Fords I have to agree that they are GREAT cars, and very reliable regardless of import propaganda to the contrary. The ZX-2 is a tremendous used car bargain and offers great reliability and very adequate performance. Congratulations on a very good car.
