Nothing has gone wrong with the car.
This car is a beauty to drive. It handles like a sports car, looks like a sports car yet is built to last a lifetime.
It rides nice on the highway and especially at high speeds, +65. Mileage, MPG, is about 24 in-town and 28 on the highway.
The car does ride low to the ground and some have difficulty getting in and out. Drive-thru restaurants and ATM machines can be a problem due to the height of the car.
What exactly is a "2+2"?
Just to define the "2 + 2" model of Z car: This model has something that can be called a back seat. I've never experienced it myself, but hear that it's good for very small children and short people with no legs. The other models don't even pretend to have a back seat.
I just bought a 1992 300zx 2+2 and I myself can say that there is not much of a backseat, little children's can fit back there, but it is mostly for insurance purposes...
