Compare used-car quotations by separating the vehicle’s full purchase price, the cost of borrowing and the payments due at each stage. Request an itemised quote for the exact car, with any loan, insurance or trade-in conditions stated. A lower advertised price or monthly instalment does not necessarily mean a lower total cost.
This StarBright Auto guide gives you a worksheet for comparing offers. It builds on our dealer-selection guide, which covers seller identity and deposit safeguards. Here, the focus is the arithmetic and the questions needed to make two quotations comparable.
First check that you are comparing the same purchase
Record the listing link or registration number, variant, mileage, COE expiry and quotation date. A price for a similar model is not a quote for the car you inspected. Note the quotation’s expiry and whether availability is confirmed.
If the cars differ, keep those differences beside the prices. An additional year of COE, documented recent repairs or different equipment can matter more than a small discount. Do not erase those differences simply to produce a neat ranking.
Ask for the price with its conditions attached
Request a written answer to this question: “What is the total vehicle purchase price if I use my preferred payment and insurance arrangements?” Then ask for a separate version if a package price is offered.
| Quotation line | What to clarify |
|---|---|
| Vehicle price | The exact car and whether the amount depends on taking a specified loan, insurance or trade-in arrangement. |
| Compulsory charges | Each administrative, transfer or other required charge, whether included already, and the total payable including any applicable tax. |
| Optional additions | The price of each accessory or service you choose, and whether it can be removed. |
| Included work | The specific repairs, servicing or items to be supplied before delivery, with a written completion commitment. |
| Deposit and balance | Which payments count towards the agreed price, their due dates, recipient and refund conditions. |
A deposit credited towards the purchase is part of the price, not another cost to add on top. Similarly, do not add an administrative fee again if the stated total already includes it. Ask the seller to reconcile the itemised lines to one total.
A worked example: compare the purchase subtotal first
The following figures are hypothetical and are not StarBright Auto prices or typical market fees. Assume the cars are otherwise comparable and both offers use the same payment conditions.
- Quote A: S$68,000 vehicle price + S$800 compulsory fee + S$600 chosen accessory = S$69,400.
- Quote B: S$69,000 vehicle price, with the equivalent fee and chosen accessory included = S$69,000.
Quote B is S$400 lower on that basis, despite its higher headline price. If you do not want the optional S$600 accessory, remove it from A and ask for B’s equivalent offer without it; do not assume B’s price will fall by the same amount.
If either offer depends on taking a different loan, this subtotal is only the first stage. Compare the borrowing costs next.
Compare finance on matching terms
Request the loan amount, duration, repayment schedule, total interest, effective interest rate (EIR), processing charges and early-settlement terms. Identify the actual lender and check the final documents before signing. A quotation is not confirmation of approval.
MoneySense explains flat rates, EIR and repayment periods. Flat-rate interest is calculated on the original amount borrowed. Its headline percentage is therefore not directly comparable with a rate calculated on a reducing balance; use the disclosed EIR and total payments.
For an illustrative S$40,000 loan at 3% a year flat interest, a four-year term produces S$4,800 interest and S$44,800 total repayment, approximately S$933.33 a month over 48 months. A five-year term produces S$6,000 interest and S$46,000 total repayment, approximately S$766.67 a month over 60 months. These simplified examples exclude fees and assume repayment to term; rounding may affect the final instalment.
The five-year example lowers the monthly amount but adds S$1,200 in interest. It is not a recommended loan, advertised rate or statement of eligibility. Use the lender’s actual schedule for your comparison, especially if you might settle early.
Keep total cost and cash needed separate
Use two views of the same deal:
- Cost comparison: full purchase price, plus financing interest and fees, plus separately budgeted ownership costs. Do not add borrowed principal again; it already funds part of the price.
- Cash-flow plan: deposit and remaining cash contribution, then instalments and other bills on their due dates. A manageable monthly payment does not tell you whether the initial payments are affordable.
For example, if a hypothetical S$70,000 purchase is funded by S$30,000 cash and S$40,000 borrowing, with S$4,800 interest and no fees, the total paid for purchase and financing is S$74,800. It is not S$114,800: adding the S$40,000 principal to the full price would count that funding twice.
Insurance, road tax, parking, fuel or charging, servicing and repairs still need their own budget. Obtain actual quotations for the relevant car and driver rather than assuming an advertised instalment covers them.
Show your trade-in as a separate transaction
Ask for the trade-in offer and any outstanding finance settlement separately. The headline trade-in amount is not necessarily the amount available towards your next car.
For illustration, a S$25,000 trade-in offer less a S$10,000 confirmed settlement leaves S$15,000 before any separately agreed charges. Get a dated settlement figure and clarify who pays the lender and when. Compare both the new car’s price and the trade-in offer; a higher allowance can be offset by a higher purchase price.
Two final questions
Should I value “free” servicing at its advertised retail price?
Only count benefits you will use and whose scope you understand. Ask what each service includes, when it expires and which workshop applies. For warranty comparisons, use our warranty questions guide rather than assigning a value to an unexplained promise.
What if the quote is still incomplete when I am asked for a deposit?
Ask for the missing lines and conditions before committing. Include any agreed professional evaluation and the consequences of its findings. CASE’s SAFE Checklist recommends professional evaluation before buying; a price comparison cannot establish the car’s condition.
For a car in StarBright Auto’s current selection, identify the exact listing when requesting a viewing and ask for the quotation details you need. Keep the final quote, agreement, financing schedule and receipts together. This is general buying guidance, not personalised financial advice.
