Long-term exotic car loans: 120, 144 and 180 months

A 120 to 180-month loan cuts the monthly payment on an exotic or collector car, but you pay for it in interest and in years spent owing close to what the car is worth. On $80,000 at 9.09% APR, going from 120 to 180 months lowers the payment by about $202 and adds about $24,750 of interest.

Who offers terms this long

Mainstream auto lenders generally don’t. The longest published terms we found on October 24, 2026 came from specialists. Woodside Credit advertises “terms up to 15 years,” and its FAQ says the length “depends on total selling price.” J.J. Best tops out at 84 months. Porsche Financial Services lists up to 84 months “in select cases.” The full list is on the lender table.

The worked example, using Woodside’s own numbers

Woodside’s site shows a set of example loans in its footer. One of them: a $100,000 price, 20% down, 144 months, 9.09% APR with its AutoPay discount. The page says rates without AutoPay are up to 0.75% higher and that its most favorable pricing goes to credit scores of 700 and above. The page shows no as-of date. This is the lender’s illustration, not an offer to you, and the arithmetic below is ours.

Assumptions: $100,000 price, $20,000 down, $80,000 financed, 9.09% APR, fixed rate, equal monthly payments, no taxes or fees rolled in.

The monthly rate is 9.09% ÷ 12 = 0.7575%. The standard payment formula, P × r ÷ (1 − (1 + r)^−n), gives:

• 144 months: $914.48 a month. Total paid $131,685.74, so total interest is $51,685.74.

To see what the term alone does, hold the rate at 9.09% and change only the length. (Woodside’s own examples use slightly different rates at different terms and prices: 9.21% APR at 120 months on a $50,000 car, 9.03% APR at 180 months on a $200,000 one. Holding the rate fixed isolates the effect of time.)

Term	Monthly payment	Total interest	Interest vs. 120 months
120 months	$1,017.31	$42,076.83	baseline
144 months	$914.48	$51,685.74	+$9,608.91
180 months	$815.70	$66,826.36	+$24,749.53

Going from 10 to 15 years saves $201.61 a month and costs $24,749.53 more in interest. Put another way, on the 180-month loan you pay back $146,826 on an $80,000 balance.

Woodside says it has no prepayment penalties, so a long term can work as a low required payment that you pay ahead of. That works only if you make the extra payments.

Whether you end up underwater depends on the car

The bigger risk with a long term is owing more than the car would sell for. Early payments on a 15-year loan are mostly interest, so the balance falls slowly. How long you stay underwater, if at all, depends on how fast the car loses value, and that varies enormously between models.

The iSeeCars 2026 study, which looked at five-year-old cars sold from March 2025 to February 2026, found the Porsche 911 lost an average of 11.1% over five years. The Porsche Taycan lost 54.7%.

Here’s the 144-month example above with each curve applied. We converted each five-year figure to an even yearly rate (about 2.3% a year for the 911 and 14.6% for the Taycan; the depreciation guide shows the math) and assumed the $100,000 price is what the car is worth on day one.

After	Loan balance	Value at 911 rate	Value at Taycan rate
1 year	$76,140	$97,674	$85,353
3 years	$67,288	$93,184	$62,181
5 years	$56,678	$88,900	$45,300
8 years	$36,685	$82,841	$28,168
10 years	$19,999	$79,032	$20,521
12 years	$0	$75,399	$14,950

At the 911’s rate, the value stays above the balance for the whole loan. At the Taycan’s rate, the balance passes the value a little after two years (around month 26) and stays above it until close to the 10-year mark (around month 118). The widest gap is about $12,000, around month 70. Sell or total the car in that window and you write a check to close the loan, unless your insurance covers the gap.

These are illustrations. A study average is not your car, and applying a five-year average evenly across 12 years is a simplification. The pattern still holds, though. On a car that keeps its value, the long term costs you interest. On one that drops fast, it costs you interest and leaves you upside down for years.

When a long term is reasonable

It fits when the car’s value curve is flat or rising, when you’re putting real money down, and when you can pay extra without penalty. It’s harder to justify on a model that loses half its value in five years, because the slow early paydown lines up with the steepest part of the depreciation curve.

A balloon loan is the other way to lower the payment. It front-loads less of the cost but leaves a lump at the end, with its own equity risk.

Run your own version

The calculator takes terms from 36 to 180 months and has presets for each model on the depreciation table. Put in the price, your down payment and the APR from a real quote, then pick the model. The shaded area on the chart is the stretch where you’d owe more than the car is worth. If you want quotes on an actual car, the quote form sends your request to specialty lenders.
