We financed with part personal loan, and the other part on 5 yrs 0% finance from the garage.
Got a really good loan rate online via co-op.
Garage were really good too as I got over 1/2 the price of the car on 0% due to the way they calculated it.
I'd shop around for personal loan 1st & see what monthly payments would be, then see how much it is on finance with garage. Be careful tho 'cos if financing thru garage as some put an annula mileage restriction on you, & avoid one with a ballon payment at end.
