My 2002 Ford is increasing in value.
I have owned my 2004 Jetcraft since 2008 and it has gone up in value about $3,500. Yamaha 115 is very dependable and I do my own maintenance. Same with 8hp Honda kicker.
All are paid for. Boat is stored in the yard. It is appreciating faster than the cost of ownership.
My 2013 Rockwood is a recent acquisition, but I have cleaned it up and added solar. It is worth a little more than I paid for it.
Buy smart and take care of your stuff. I pay cash with $100 bills.
The cost of ownership is nil.
