I'm looking to buy a used 2008 Glastron GT 205 with the 5.0L Volvo Penta (220 HP). The boat has about 30 hours, trailer included, and has the XL package. I went and test drove the boat and it is in great condition. The seller is trying to get $22,750.00, which includes life vests, skis, kneeboard and tube. Is this a good deal?
