One more car to seriously check out... the EVO. I drove an evo on a TIGHT 360 degree donut highway exit at 75mph. Can't do that in my Z. 60mph is all I can do on a donut on a stock Z. And I'm basically drifting at that point... the EVO can manage that feat while planted.
But the Z still wins in my book in overall quality.
A used ipl is also a better car to cross shop... check it out. Sub 43k pricing on lightly used ipl's. Ipl's go for about 50-52k before TTL AND FEES.
