Yes, I'm Stingray savvy. Our family ran Stingrays for the past 35 years. All 19-21 feet. IMHO, a V8 is a waste of money, unless you just want bragging rites. My 4 banger 3.0 was an awesome engine. My son's V6 was good, but not much better. You have to understand that Stingrays are designed to run better with less HP.
I laugh at the comments about harsh ride. My new SeaRay is significantly heavier and more HP, (and the ride is awesome), but my old Stingray rode just as well.
I also have experience with Porches. If you are satisfied with that ride (and i don''t know why), the Stingray ride won't bother you at all.....LOL.
OTOH, recent Glastrons are not what I would consider a value product.
As far as color, I can't comment. I only buy new and order whatever the Admiral wants.
Finally, go Merc. Volvos are not bad, but try to find a dealer to service it and you'll understand why Merc is the best choice.
