Is insurance cheaper for a newer/smaller car with smaller engine or an older/bigger car with a larger engine?

Engine size is actually only a small consideration when insurance companies give you a quote. That mostly applies to high-performance vehicles, like a Ferrari or old muscle car, such a 1970 Hemi 'Cuda. What determines insurance rates is the average rate at which the make/model of your car is stolen, how old it is, how expensive it was, your driving record/age and the average crime rate in your area. Both of the vehicles you listed have high theft rates, but I think the Honda ranks higher, so I am guessing it costs more.
