01
Depreciation and warranty trade-off
New vehicles typically lose the most value in the first three years; used vehicles three years old or older have absorbed that depreciation curve. New vehicles come with full manufacturer warranty starting fresh; used vehicles have variable remaining warranty depending on age, mileage, and CPO status. The household trades depreciation cost for warranty coverage when buying new, and trades warranty risk for absorbed-depreciation savings when buying used.
02
Financing rates and tax timing
New car financing typically gets lower rate bands than used at the same lender for the same buyer credit tier; used financing rates are higher because the collateral carries more depreciation risk. California sales tax is collected on the full purchase price up front for finance and on each lease payment for lease; the tax structure differs by path, not by new vs used. The cash-flow timing affects the household budget meaningfully.
03
Which household fits new
New fits households that value full warranty from day one, want the latest safety and infotainment technology, plan to keep the vehicle long enough that the depreciation difference flattens, or have program-window incentive structures that offset early depreciation. New also fits when the configuration is genuinely scarce in the used market.
04
Which household fits used or CPO
Used and CPO fit households that are cost-sensitive and willing to absorb some warranty risk, the configuration is widely available used, the household plans to turn over the vehicle in three to five years, or the new-car configuration is allocation-limited. CPO programs add extended warranty coverage that reduces ownership risk versus a private-party used purchase.

FAQ
Common Questions
Is buying used always cheaper?
Cheaper on cap cost typically; not always cheaper total when accounting for higher financing rates, potentially higher repair costs out of warranty, and the household's risk tolerance.
Is CPO worth more than regular used?
Often yes when the CPO program adds extended warranty and inspection certification. The CPO premium reflects added value, not pure markup.
Does leasing change the new-vs-used calculation?
Yes. Leasing covers depreciation over the term rather than absorbing it through resale; the household never realizes the depreciation hit because the vehicle returns at lease end.
Which is better for California sales tax?
Lease structure spreads sales tax across periodic payments versus financed purchase taxing the full price up front. The new-vs-used distinction does not change the tax structure; the lease-vs-finance distinction does.
