I considered a ZL1, but the manual cars suffer from a bog that occurs when pulling away from a stop (supposedly from an over sensitive torque management system). No permanent fix as of yet, other than a tune. Then there's the poor outward visibility. These issues swayed me toward the M2C. No regrets...while the M2C isn't as quick as the ZL1, it's quick enough to be fun, and I prefer its smaller dimensions and lighter weight. I would've enjoyed the ZL1's blower whine, though.
