How We Score

No guesswork. No AI opinion. Just data.

Why these 8 things?

When you buy a used EV in Singapore, you're really making 8 bets at once: How fast will it lose value? Can I sell it later? Is the battery still good? Will the tech hold up?

We score each of these from 0 to 100 using real data — sgcarmart listing info, COE prices, warranty records, and Singapore-specific market data. Then we combine them into one number. The score is calculated purely from numbers, not AI. The AI only writes the explanation afterward.

The 8 Dimensions

20%
How fast does it lose value?
Depreciation & Equity

Uses sgcarmart's published depreciation figure — how many dollars the car loses each year. Lower is better. This gets the heaviest weight because depreciation is the single biggest cost of owning a car in Singapore.

20%
How easy is it to sell later?
Resale Liquidity

A Tesla Model 3 sells in a week. An obscure Chinese EV might sit for months. We check brand popularity in Singapore, service network availability, and whether it's Cat A or Cat B.

15%
Is the battery still healthy?
Battery Risk

Replacing an EV battery costs $15-30K — you don't want that surprise. We check warranty time left, km left, battery chemistry (LFP batteries last longer than NMC), and current mileage.

15%
Will the tech hold up?
Tech Obsolescence

EV tech moves fast. Can the car receive software updates (OTA)? Does it have decent driver assistance? Is it a current or pre-facelift model? How fast can it DC charge?

10%
What does it actually cost to run?
Total Cost of Ownership

Depreciation plus everything else: insurance (with NCD), electricity, maintenance, road tax, and parking. Some EVs look cheap but cost a lot to insure.

10%
Can I exit without losing money?
Exit Optionality

If you need to sell in year 2 or 3, will you owe more than the car's worth? We check every exit year and calculate whether you'd break even or better.

5%
Did it lock in good rebates?
Rebate Alpha

EVs registered before 2026 got up to $40K in rebates (EEAI + VES). Those rebates are baked into the car's value — more captured = better deal for you.

5%
Does it fit my budget?
Financing Fit

How does the monthly loan payment compare to the budget target? Well under budget scores high, over budget scores low. You can adjust the budget on any listing page.

What the Scores Mean

84+ STRONG BUY Outstanding deal — rare
78–83 GOOD BET Solid choice — worth a closer look
70–77 MIXED BAG Has some strengths, but also concerns
<70 REJECT Too many red flags — skip it

What We Can't Score

  • Actual car condition — We can't see dents, paint quality, or real battery health. Always inspect in person or get a pre-purchase inspection.
  • Dealer trustworthiness — Some dealers are better than others. Check reviews on sgcarmart and ask around.
  • Your personal preferences — Ride comfort, boot space, brand feel — only you can judge these.
  • Future policy changes — COE quotas, rebate changes, and road tax adjustments could shift the math.

The score is a starting point — it helps you narrow down the shortlist, but always do your own homework before signing anything.

Built for Singapore

This isn't a generic car scoring tool. Every formula accounts for Singapore-specific factors: COE cycles, PARF rebates, Cat A vs Cat B pricing, local insurance costs, electricity tariffs, and the unique dynamics of the SG used EV market. The data is updated with each COE bidding round.
