New to Alfa Romeo and wanna know everything maintenance wise

So a co-worker of mine at my new job had an Alfa Romeo Guila and the brand been absolutely stuck in my head for almost a year now.

I plan on getting my own Guila (pre-owned) within a year or 2 from now and I wanted to know about all the maintenance I need to be aware and how I can be up to date on everything.

I know this brand gets a lot of hate for being unreliable but I also know that cars like this reward you for how well you take care of them. I also wanted to know if finding a mechanic who works on these cars is better than going to the dealership for service.
