Need info on Ranger Z series boat

Particularliy the 21 - 22 ft lengths. Have a buddy that is considering buying one and needs input from a present owner on perfomance, ride, issues, etc. Not looking for an argument or brand war about boat brands or why another brand is better. Just some straight up info from anyone that has or had one. All and any info on likes, dislikes, what they think could have been better, etc. Thanks in advance for any replies.
