I have always owned a MC. I grew up with a 1989 Pro Star 190, then a new 2000 X-Star and most recently the 03 X-Star. I have been very happy with all the boats and experienced very few problems throughout the yrs. Throughout the yrs my needs have changed. I still really like the X-Star and would purchase another one. However I wouldn't get it without the L-18 engine. After pricing them out, the price difference between a new 05'X-Star with the L-18 and the 05' SANTE with the ZR6, was enough to get me interested. This has been a very hard decision based on the dynamics of the two boats, size, storage, style, dealer relationship (I really like my MC dealer, Action in Hudsonville MI.)etc. Just so you know the price difference was about $20000. Maybe more like $15000 when its all said and done after I add (2) NVS 808 tower speakers, additional amps, closed cooling system shower, and tower lights. Im just looking for a change. I want to load down that boat until it struggles to plan off. With the ZR6, the wake should be kickin...
