Bought a new astro 18sc in 1990. It was the cheapest boat as far as repairs. It was in the shop twice in 25 years for minor repairs to be done. I changed my own water pumps and did most of the maintenance. Only reason that i sold it was i am getting older and it got to be a hassle loading and unloading. New is the best way to go if you can afford it. I agree that you need a lot of cash to put down or a very good trade-in. Fifteen years is a long time to finance something, unless it had doors and a roof.
