The Mazda 121 is a small car that has long left the showroom. If you have one, or are thinking of buying one, the costs that matter are the yearly ones. This guide covers the COE rule, road tax and car insurance in Singapore.
The insurance figures are examples for one stated driver, as of 1 November 2026. They show how prices compare. Your quote depends on your details and your car.
The version the prices cover
The new-car list has no entry for the Mazda 121 on sale now. So this guide gives no list price, power figure or body type.
The price page prices the Mazda 121 1.3, with a 1,299cc engine. It is the version most insurers quote. Check that the car you have or want matches it.
COE
The price page gives the rule for the 1.3. With its 1,299cc engine, it needs:
- Category A if its power is 97kW (130bhp) or less. Category A closed at S$132,004 in the October 2026 2nd round.
- Category B if its power is more. Category B closed at S$131,901 in that round.
For a car this old, the COE already paid is the main question. Check how much of it is left, and whether it has been renewed before. The COE page has the latest results.
Road tax on a 1,299cc engine
Road tax follows engine size. For the 1,299cc engine, LTA's formula gives S$566.36 a year, before any age surcharge.
Older cars pay a surcharge on top:
- Over 10 years: +10%
- Over 11 years: +20%
- Over 12 years: +30%
- Over 13 years: +40%
- Over 14 years: +50%
On an older car, the surcharge can make a real difference to the yearly bill. The road tax page works out the full figure.
Insurance for the standard driver
The Mazda 121 price page prices one set of details:
- Car: Mazda 121 1.3, registered 3 years ago, private use, comprehensive cover
- Driver: aged 40, married, office job, driving 10 years
- Record: 50% no-claim discount (NCD), no claims
- Repairs: authorised workshop, no options
8 insurers price it online, across 13 plans. The lowest premium is S$704.25 a year. The insurer whose lowest plan costs most asks at least S$1,177.72, marked as an estimate. That is S$473.47 more, or 67% on top. The dearest plan on the page is S$1,531.04. All prices include 9% GST.
The page uses a car 3 years old as its standard. If your car is much older, look at the 8-year-old figure below as well.
A wide range of excesses
The excess is the part of a claim you pay. On this page it runs from S$500 to S$5,000. Most plans carry S$600. The lowest premium has a S$1,200 excess, and the second lowest has S$5,000. So a low premium can come with a large bill if you claim.
How the premium moves
The price page shows the lowest price when one thing changes:
- No NCD (0%): S$1,531.04, S$826.79 more
- 20% NCD: S$1,183.14, S$478.89 more
- Driver aged 27, 3 years' driving, 30% NCD: S$1,584.28, S$880.03 more
- Driver aged 65, 20 years' driving, 50% NCD: S$915.29, S$211.04 more, with 7 insurers pricing
- New car, registered this year: S$749.19, S$44.94 more, with 6 insurers
- Car 8 years old: S$689.26, S$14.99 less
The young driver case is the costliest, up 125%. Losing your NCD lifts the price by almost as much. An older driver also pays a little more. An 8-year-old car comes in slightly lower than the standard figure.
For a small, low-cost car, these jumps are large next to the premium itself. A young driver can pay more than twice the standard price. If you are adding a younger driver, ask for a quote with them named before you decide. Fewer insurers price some of these cases, so the field narrows too.
Against similar small cars
For the same driver and car age, the price page sets six cars beside the 121:
- Mercedes-Benz GLB: S$822.26
- Mercedes-Benz GLA: S$822.26
- Mercedes-Benz A-Class: S$755.55
- Honda Jazz / Fit: S$741.66
- Toyota Yaris Cross: S$704.12
- Toyota C-HR: S$689.29
Their average lowest price is S$755.86. The Mazda 121 costs 7% less than that. Two of the six are cheaper to insure, both by small amounts. The rest cost more.
Other Mazda models are on the Mazda car insurance page. The cheapest cars to insure list shows where small cars sit overall.
Costs that depend on you
- Parking: season parking at your HDB block or condo, plus parking elsewhere.
- Petrol: depends on how far you drive and pump prices.
- ERP: set by the roads and times you use.
- Repairs and parts: on an older car, parts supply and wear items matter more. Ask for the service history.
- Depreciation: on a car near the end of its COE, value depends mostly on the COE years left.
