I see that the responses so far have not been too helpful yet.
If you missed it, here is a post I posted in another thread the other day:
Although we don't have an Alfa, we have two separate friends who do and who love them (well, one has a love/hate relationship with theirs but we all have that to a certain extent, don't we? *lol*).
Pertaining to the company being out of business, I suppose that could pose some problems on one hand but not that big of a deal when you really think about it. Most likely, the units out there would be out of warranty anyway. And as I say, those two shops I referred to have great reputations amongst Alfa owners in fabricating parts and knowing the ins and outs of the See Yas.
Although we have a Winnebago and it is indeed nice to call their customer service number to get advice and suggestions for problems, if you get to know the personnel at either of those two shops, I'm sure they'd gladly give you the same type of advice and suggestions. It may be nice to have the factory to fall back on when a big problem occurs or to have a place to take the coach back to in order to deal with issues in an absolute correct manner, but again, we don't think it is absolutely necessary in an older coach.
I don't know where in California you are but if in the southern part of the state, Alfateers is really a great place. We've been there just to look around and the people who work there are great. You'll also find them at many of the rallies roaming around fixing things for Alfa owners. It's like a mini-factory there as they do a lot of custom body work as well as mechanical stuff and modifications.
If you are in the northern part of the state, you might be closer to Charlies in the SLC area who our friends swear by. They do lots of work on Alfas and have quite a following amongst Alfa owners.
