FAQ

Frequently asked questions

When does cash back typically win?

When the gap between the promotional rate and the standard rate is small, or the loan term is short, the upfront rebate often wins.

When does low-interest financing typically win?

With longer loan terms and a large gap between promotional and standard rates, the interest savings can outweigh a modest rebate.

Can I negotiate the price separately from the financing offer?

Often yes — try to negotiate the vehicle price first, then evaluate financing offers independently for the clearest comparison.
