First car - '98 Prelude (base) w/bolt-on's. Great first car, the only thing I had to fix on the car was my driver side window... it popped/jumped off the track. I learned a lot from working on this car, and I made a lot of good friends when I had it.
Second car - '06 M35 S w/intake, exhaust, uprev. This car spoiled me silly! 14 speakers, heated+cooled seats, adaptive headlights etc. But man!! was this thing ever thirsty! I would average 13mpg in the city! 16mpg when I'm concious of my right foot in mixed driving.
Third and current car - 40th Anni. Ed. 370z
