When buying from a dealer, it's worth asking for a finance quote directly from them. Before that, though, get a loan quote from Rahalaitos too: it gives you something to compare the dealer's offer against, and a way to negotiate better terms.
Viewing quotes is free and doesn't commit you to anything. Rahalaitos puts your application out to as many as 25 lenders at once.
