How Manufacturer Buybacks Are Calculated

How Manufacturer Buybacks Are Calculated in Michigan

A Michigan lemon law refund starts with your purchase price, adds back certain charges the manufacturer collected, then subtracts a mileage-based usage allowance and any damage not related to the defect. Each piece of that calculation comes from a specific part of the statute, and getting any one of them wrong changes the final number. This page walks through every step with a full worked example, so you can see roughly where your own number is likely to land before a manufacturer’s representative tells you their version of it.

Start With the Purchase Price

Under MCL 257.1401, purchase price means the actual vehicle sales price listed on the buyer’s order, including any cash payment you made and the dollar value of any trade-in allowance, but excluding debt carried over from an unrelated transaction. This is the sticker level number from your original deal, not your current loan balance and not what you still owe today. A trade-in allowance you received when you bought the vehicle counts toward the purchase price even though you did not pay it in cash, since the statute treats it as part of what you gave up to acquire the vehicle.

The purchase price also includes sales tax, license and registration fees, and similar government charges you paid that are not already counted elsewhere in the deal. These are easy to overlook if you focus only on the vehicle’s sticker price, but they are part of what you are entitled to recover, and we itemize them separately on every buyback worksheet so nothing gets lost in a lump sum negotiation.

Add Back Certain Charges

Michigan’s statute also lets you recover the amount of other charges made by or for the manufacturer, which in practice generally includes finance charges tied to the deal and a partial share of extended warranties, GAP insurance, credit or disability insurance, and other dealer add-ons sold alongside the vehicle.

These charges get folded into the calculation because they were part of what you paid to acquire and finance the vehicle, not separate optional purchases unrelated to the defective unit. We request the full finance contract and any add-on product agreements early in a case specifically to identify every charge that belongs in this part of the calculation.

The reimbursement for products like an extended warranty or GAP insurance is generally partial rather than full, since you received some benefit from that coverage for the time you actually owned and used the vehicle, similar in concept to the mileage offset applied to the vehicle itself. A warranty purchased for the full term of ownership that you used for eleven months before a buyback is treated differently than one purchased the week before the buyback was finalized, and we calculate this proportional piece separately from the vehicle’s own mileage offset.

Subtract the Mileage Offset

The law allows a deduction for the mileage you put on the vehicle before it became clear something was wrong, using a specific formula. The offset equals the purchase price multiplied by a fraction, with 100,000 miles as the denominator and the numerator equal to the miles attributable to your use before your first report of the defect, plus any mileage beyond 25,000 miles attributable to your use at any point. If you reported the defect at 5,000 miles and never exceeded 25,000 miles in total, the calculation is straightforward: 5,000 divided by 100,000 equals five percent, so a $20,000 purchase price carries a $1,000 mileage offset.

Mileage the dealer put on the vehicle before you took delivery, mileage driven to and from service appointments, and mileage from a previous owner before your purchase are not counted as mileage attributable to your use. We review service records and delivery paperwork closely when a manufacturer’s mileage figure looks inflated, since this is one of the more commonly disputed numbers in a buyback calculation.

Subtract Any Damage Not Related to the Defect

The purchase price is also reduced by an amount equal to any appraised damage that is not attributable to normal use or to the defect or condition itself. Door dings, dents, scratches, glass damage, or missing equipment will generally be deducted at the dealer’s repair cost, which tends to run higher than what an independent body shop would charge. We generally recommend repairing minor cosmetic damage before a repurchase date if it is cost effective to do so, and filing an insurance claim for more significant damage, since either option is usually less expensive than the deduction a dealer appraisal would apply.

A Full Worked Example

Combining every piece above into one example makes the math easier to follow. Assume a vehicle purchased for $28,000, with $1,200 in finance charges and extended warranty costs included in the deal, 6,000 miles driven before the defect was first reported, no mileage beyond 25,000 total, and $400 in appraised door and bumper damage unrelated to the defect.

Purchase price (per buyer’s order)$28,000
Plus: finance charges and add-on products+ $1,200
Subtotal$29,200
Less: mileage offset (6,000 / 100,000 = 6% of $28,000)– $1,680
Less: unrelated appraised damage– $400
Estimated net refund$27,120

Your own numbers will differ based on your purchase price, financing details, mileage, and condition, and a manufacturer’s first offer frequently omits charges you are entitled to or overstates the mileage or damage deductions. We recalculate every buyback offer from scratch rather than accepting a manufacturer’s figure at face value.

How Leased Vehicle Numbers Work Differently

A leased vehicle does not have a purchase price to start from, since you never owned it outright. Instead, the calculation generally starts with the lease payments you have already made, including any down payment or cap cost reduction at signing, and the resolution also addresses payoff of the remaining lease balance so you are not left owing payments on a vehicle you no longer have. The mileage offset and damage deduction concepts still apply in principle, but they are measured against the lease payment total rather than a purchase price, which changes the final numbers even when the vehicle and defect look identical to a purchased case.

Common Mistakes in a Manufacturer’s First Offer

A manufacturer’s first buyback number is a starting point for negotiation, not a neutral calculation. The mistakes we see most often are a mileage figure that includes miles driven by a dealer or a previous owner, a purchase price that leaves out sales tax or a trade-in allowance the consumer is entitled to include, a damage deduction based on a dealer’s inflated repair estimate rather than a fair market repair cost, and finance or add-on charges left out of the calculation entirely.

Each of these mistakes tends to move the number in the manufacturer’s favor rather than yours, which is why we rebuild the calculation independently rather than starting from whatever figure a manufacturer’s representative provides.

What About Attorney Fees

Attorney fees and costs are generally recovered separately from the manufacturer under MCL 257.1407 when a consumer prevails, rather than being deducted from your refund. This fee-shifting structure is why pursuing a lemon law claim with an attorney typically does not reduce the net amount you walk away with, and it is a meaningful part of why we take these cases on a no-fee-unless-we-recover basis.
