My first Malibu Response, a 2005 closed bow, was sent back to the factory after one summer of usage because of hull/gelcoat issues. It was then refurbished and sold by Malibu again. I heard, it serves as a club boat somewhere in the US. I think @buechsr knows more about it.
My 2006 Response lives in Texas now. It’s been used on Lake Austin and Lake Travis.
We visited the guy who bought it from us a few years ago and he took us out for a ride. Was awesome to see that the boat is still in great condition and he and his wife are enjoying it a lot.
Our 2010 Response was bought by someone who lived not too far from us. Never heard back from him or seen that boat again, but mutual friends told us, that he already sold it again due to not using it that much. He probably made a nice profit given the crazy boat market these days. (I sold it right before that whole covid thing went off and in retrospective I should have held on to it a little longer. Could have easily sold it for about $8k more had I only waited a few months longer.)
