I love my Z but in all honesty, if Honda still produced the S2k and I could pick one up today NEW from the factory I would get it in a heartbeat. Give me an AP1 engine but with the glass rear window from the AP2 model and I will happy.
I drove one a couple years back but it would have been financially irresponsible for me to get one being fresh out of college w/ loans to pay off etc. The S2k may not have the power of the Z but it is the quintessential roadster/sports car made in the last decade IMHO. Nothing like ringing out a car for every ounce of power while the revs climb to 9k rpm.
