Yes, down payment matters, but it also depends on WHAT you drive. If you are content driving anything with 4 wheels and a seat, then your payments will be cheaper. If you like something more, then you expect to pay more. I have one car that we paid cash for (convertible Sebring), one that I have a $369/mo (Durango), and DS20's Mustang at $375/mo. I did have DD19's Mustang too at $584/mo but she just traded it and got herself a Lincoln MKX in her own name.

That doesn't include DH's cars or motorcycles.
