This kind of setup is a decent investment some where around $500 which is a pretty decent value for a transportable boat that can hold a family of four and has a motor.
The next options is this Lifetime or Vibe Skipjack Kayak
Both have decent reviews but to be honest I'm over loading stuff on my car. I did it with my Native and it was doable but I can't say I enjoyed it after a day on the water. I'm leaning towards the inflatable boat and installing a wood floor to go inside of it. We'll see what happens I may end up not getting anything. It's fun to shop but it would be more fun to use one of these boats out on the water. I haven't been fishing in awhile. We've had a real heat wave lately with 100+ heat index and horrible humidity.
