1990 Correct Craft Sport Nautique

Me and my friend are 16 years old and love to wakeboard. We recently found a 1990 Correct Craft Sport Nautique. The boat has 280 original hours, has been in storage for the past years and is in immaculate shape. The bottom has been painted. We can pick it up for what seems to be a great price, $3000. The boat needs a tune-up along with some changes such as the battery and possibly the starter and also needs 2 new belts but the seller is willing to take care of all this. We saw the boat yesterday and it looks great. How well will this boat hold its value 6-10 years from now? Good investment? Please let me know your take as soon as possible and THANKS SO MUCH!
