The 08LSV has the current gen hull (the ride is the 04-07 LSV hull) and bow ballast, which makes it the better choice. Titan tower is also preferred (from a 'core perspective, though probably not to the tube pulling public). The 08 LSV dash is probably the ugliest Malibu ever made, and it's the only year for that dash on that boat.
I'd guess the 08 would be a good deal if it could be had for under $50k. On the Ride, it's really about how you value the hours. There are certainly 07 LSVs (same as 09 Ride 23) out there with power wedge, quad ballast, etc., for mid 40s with reasonable hours. An LSV will have much nicer vinyl, dash, and assorted bling/intangibles than the ride too.
