How we put a price on a car feature
Every verdict on this site comes from one calculation: what the features you gain between two variants are worth, against what the variant costs extra. That only means anything if you can see the numbers and argue with them. So here they all are — all 76 of them, what each is valued at, and why.
It is not what the feature costs the manufacturer
Nobody outside a carmaker knows what a sunroof costs to fit on the line, and it would not help you if we did. What matters when you are standing in a showroom is different: what is this worth to me?
So each figure is our estimate of what a feature is worth to a buyer who wants it — benchmarked, wherever possible, against what it would cost to get that feature another way.
Can you add it later, or not?
This is the question that decides how a feature is valued, and it is the most useful thing to know before paying for a trim.
You could add it afterwards
Alloy wheels, a touchscreen, seat covers, a reversing camera. The aftermarket price anchors the value, because that is your alternative. If a variant upgrade charges far more than the fitted aftermarket cost, the lower trim plus a visit to an accessories shop is usually the better buy — and our verdict will say so.
It has to come from the factory
Side and curtain airbags, stability control, ADAS, a sunroof aperture, ventilated seats, LED headlamp assemblies. These are wired into the body or the ECUs and cannot be added later at any sensible price or safety standard. If you want one of these, the trim that has it is the only way to get it, and that is reflected in the value.
How firm is each number?
Every valuation below carries one of three labels, and the count is what it is — we would rather show you which numbers are soft than present all 76 as equally solid.
- high · 27
- Priced against something you can go and buy today.
- medium · 30
- A reference point exists, but not for the identical item.
- low · 19
- No purchasable equivalent — an estimate of worth, not of cost.
Each valuation also carries the date it last changed, taken from this repository's own history rather than asserted — a freshness claim nothing backs is worse than no claim at all.
The same feature is worth less on a cheaper car
A sunroof on a ₹6 lakh hatchback is not worth what it is on a ₹20 lakh SUV — the buyer is more price-sensitive and the feature is a larger share of the car. Every value below is quoted for a mid-size SUV and scaled by segment:
What the share of the price gap has to reach
We add up the features you gain, subtract anything the higher trim drops, and express it as a share of the price gap. That share is what the verdict is based on.
We only price the equipment that differs between two variants. The rest of the price gap pays for things we deliberately do not itemise — upholstery and trim materials, fit and finish, badging, and the manufacturer's own margin. So a share below 100% is normal, and for a long time our feature list was thin enough that no variant could reach it.
That changed in September 2026, when we added the 27 items that separate a base trim from the one above it — remote locking, a speaker system, wheel covers, a rear defogger, armrests, a day/night mirror, automatic headlamps — along with the extras at the top of a range. The list now covers enough of a real variant upgrade that we can ask the honest question: is the equipment worth what the variant costs extra?
- Worth it100% or more
- The equipment alone covers the price rise. If you want any of what it adds, buy it.
- Fair upgrade60% to 100%
- Reasonable if you specifically want what it adds. Not a bargain.
- PriceyUnder 60%
- You are mostly paying for something other than equipment. Look hard at the list.
These bands are a property of how completely our feature list captures real trim equipment, so they are re-derived from the data whenever that list grows — never moved to make the numbers look better. They were 75% and 45% against a 49-feature list; filling the gap at the bottom of a range raised the typical upgrade from about 60% to 85%, which left most upgrades sharing one verdict. At 100% and 60% the upgrades spread evenly again, and the thresholds say something plainer than the old ones did.

Comfort & convenience
- Dual-Pane Panoramic Sunroof ₹55,000
- Factory-onlylow confidenceCutting a roof aperture afterwards compromises structural rigidity. The most-requested feature in this segment, which is why it carries the highest comfort value here.Last reviewed 10 Sept 2026

- Automatic Climate Control ₹12,000

Infotainment & connectivity
- Retrofithigh confidenceLittle credible aftermarket equivalent at this size, so priced closer to what the trim upgrade charges than to a retrofit.Last reviewed 10 Sept 2026

- Factory-onlylow confidenceEither a combiner and projector built into the dashboard or a treated windscreen. Stick-on aftermarket units are not the same thing.Last reviewed 16 Sept 2026
- Retrofithigh confidenceA comparable aftermarket head unit fitted costs roughly this much, so the factory unit is worth about the same to a buyer who would otherwise fit one.Last reviewed 10 Sept 2026
- Connected Car Technology ₹12,000
- Factory-onlylow confidenceNeeds an embedded SIM and a telematics unit wired to the car's systems. Valued for the hardware only — most makers charge a subscription once the free period ends.Last reviewed 16 Sept 2026
- Factory-onlylow confidenceThe cluster is bound to the car's CAN bus and odometer. Priced at half the full-width unit, which replaces the dials entirely.Last reviewed 16 Sept 2026

- Retrofithigh confidenceA basic head unit and a pair of speakers fitted costs about this. Set only where the trim has no touchscreen, so it is never counted alongside one. Priced at the low end because what qualifies ranges from a two-speaker dock to a four-speaker system.Last reviewed 16 Sept 2026
- Factory-onlylow confidencePart of the dashboard and the climate module.Last reviewed 10 Sept 2026
Exterior & wheels
- Retrofithigh confidencePriced as the upgrade from a 17-inch wheel. Worth knowing that bigger factory wheels also mean more expensive tyres for the life of the car.Last reviewed 17 Sept 2026

- Retrofithigh confidenceA set of comparable alloys costs about this fitted, which is why buying a lower trim and changing wheels is often the better move.Last reviewed 10 Sept 2026

What we would want you to know before trusting it
- These are judgement calls, not survey data. They are informed estimates benchmarked against aftermarket pricing where an aftermarket exists. They are not the output of a study of what buyers pay.
- The list is incomplete. 76 features do not capture everything that separates two trims, and coverage is thinnest at the bottom of a range, where trims differ on many small items. A base-to-second-trim upgrade will usually score worse than it deserves.
- A feature you do not want is worth nothing to you. We value a sunroof highly because most buyers in this segment want one. If you never open it, ignore that line and read the rest.
- Prices move. Every model page carries the date we last checked its prices against the manufacturer, and which powertrains its variant list covers.
