Stuart, I have to say that it's been our experience that the S 4's have been very reliable. sure they take maintenence, but we're not talking ( or wanting to drive) Honda accords or toyota Camrys. I really don't feel that an S4 needs to be more expensive to repair than anything else. ie $ 431 to replace the fuel pump and braket in the tank for my 88 chevy S 10. Is the A 4 big enough for your height?
