The Alfa Romeo 166 is a large older sedan that has left the new-car list. Few insurers price it online, and its 3.0 V6 engine sets a high road tax. This guide lays out those costs for owners and anyone thinking of buying one used.
Insurance figures are examples for one stated driver, as of 1 November 2026. With only two insurers pricing it, they are a narrow sample.
What the facts cover
The new-car list has no entry for the 166 on sale now. So this guide gives no list price, power or body type. The price page shows insurance prices, the COE category and the engine size.
The quote form lists one version, the 166 3.0 V6 with a 2,959cc engine. The insurance prices are for that version.
Road tax for a 2,959cc engine
Road tax follows engine size. LTA's formula, checked 2026-10-19, gives S$2,337.00 a year for the 2,959cc engine, before any surcharge.
A surcharge is added once a car is over 10 years old:
- Over 10 years: +10%
- Over 11 years: +20%
- Over 12 years: +30%
- Over 13 years: +40%
- Over 14 years: +50%
On a large engine, each step adds a large sum. The road tax page explains the formula.
COE
With its 2,959cc engine, above 1,600cc, the 166 needs a Category B COE. Category B closed at S$131,901 in the October 2026 2nd round.
For a car this old, the years left on its COE matter most. They set how long you can keep it without renewing. The COE page shows later results.
Insurance on two prices
The Alfa Romeo 166 price page prices:
- Car: 3.0 V6, 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
2 insurers price it. The lower price is S$2,897.48 a year with a S$1,200 excess. The other is S$3,007.15 with a S$300 excess. The gap is S$109.67, or 4% more. All prices include 9% GST.
The two plans trade a small premium gap for a big excess gap. If you expect to claim, the plan with the lower excess may cost less overall. If you rarely claim, the lower premium may suit you.
The page lists 13 insurers with no online price for the 166. Most have no price for the model yet. One does not offer this cover online, and one holds a price for one standard driver only.
How the price moves
The lowest price when one detail changes:
- No NCD (0%): S$6,664.21, up S$3,766.73
- 20% NCD: S$4,867.78, up S$1,970.30
- Driver aged 27, 3 years' driving, 30% NCD: S$7,279.83, up S$4,382.35
- Driver aged 65, 20 years' driving: S$1,482.37, down S$1,415.11
- New car, registered this year: S$3,082.38, up S$184.90
- Car 8 years old: S$2,835.79, down S$61.69
A young driver faces a rise of 151%, the biggest change here. The no NCD, 20% NCD and young driver lines are each priced by just 1 insurer.
The older driver line stands out. For a driver aged 65 with 20 years' driving, 5 insurers price the car, and the lowest price falls well below the standard driver's. So more insurers are open to that profile on this car. If you are an older driver, it is worth comparing several quotes.
The car age lines move far less. A new car adds S$184.90, and an 8-year-old car takes off S$61.69. A real 166 is far older than either, so neither line tells you exactly what you would pay. Each line also tracks the lowest price only.
Points to check on a used 166
- COE left: it sets how long you can keep the car.
- Road tax band: the age surcharge may already apply.
- Quotes before you pay: with two online prices, ask insurers before you commit.
- Service records: they help you judge what work may be due.
Against similar cars
The price page sets the 166 beside six cars with engines of about 3 litres, same driver and car age:
- Audi Roadjet Concept: S$1,524.39, 1 insurer
- Audi Q8: S$1,323.18, 8 insurers
- Audi S4 Saloon: S$1,209.34, 8 insurers
- Audi S5: S$1,209.34, 8 insurers
- Audi A8: S$1,092.69, 11 insurers
- Audi Q7: S$1,002.60, 14 insurers
Their average lowest price is S$1,226.92. The 166 costs 136% more than that, and all 6 are cheaper to insure on these details. Part of the gap reflects how few insurers price the 166. The Alfa Romeo car insurance page lists other models.
Owner-set costs
- Parking: season parking at home and parking elsewhere.
- Petrol: depends on how far you drive and pump prices.
- ERP: depends on your routes.
- Servicing and parts: ask what a workshop can source for this model before you commit.
- Depreciation: follows the price you pay and the COE left.
