Nice. Most of those are pretty damn reliable. The early NAs are known to have the short nose crank issue. I am not sure if they solved that in yours. I think it looks a NB from your pic.

I had an NA, under power is an understatement, but no need to use brakes on turns so you save gas and it just keeps on going. Mine had sticky tires and adj Tokico shocks on it. Oh one more thing to remember, do not ever allow those soccer moms to beat your ass to the next signal light. They do this without trying and probably don't notice what they are doing to your manhood by making you look bad in your lil' red sports car. Mine was red also. They really are lots of fun. I took mine to a Porsche canyon run a couple times. They all gave me the thumbs up and all smiles, but I know deep down inside those bastards were calling me all kinds of names once I got into the car
. Oh and I know them well.
