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.

The amount repayable would then be €10,215, i.e. €94/month. A credit card's APR may be 18.97%, calculated for a loan of €1,500 with a repayment period of one year and a nominal interest rate of 17.50%. The amount repayable would then be €1,646 in total, i.e. €146 per month. The final APR, loan term and monthly instalment are set out in the loan agreement.
