We have a 83 Bestway Labelle 42 feet with twin Volvo TAMD40As with 2800 hours on them, always start up, run great. As for parts, Volvo Penta parts are expensive BUT there are a lot of replacement options that are not. Example, we had to replace an oil cooler, volvos price $2800, generic part $280. There was some leakage around the windows which we fixed, other than that it is solid trawler, lots of teak in the earlier models which we restored and plenty of room in the salon, the aft master bedroom and we love the stern space. BUT get an engine surveryor as well as a boat surveyor, you can save thousands. Low hours don't always mean good, we looked at a boat that had only 300 hours in 10 years, talk about replacing gaskets, hoses etc. Good Luck
