I have a freind looking at a 40 Express and I'm looking for any opinions on this boat. The one specifically he's looking at is a 1994 in Michigan with T-454 gas engines and 1000+ Hours. IT appears to be in great shape, but I'm telling him to budget in an engine overhaul for the future, and it's priced accordingly. Was there any major flaws with this design? For him, the biggest selling point for the Express over the DA is the bunks vs. the mid-cabin layout.
