Fix anything that blocks the RMV transfer (revenue licence, VET, insurance) and cheap, visible faults — skip expensive mechanical overhauls, since most buyers deduct less from the price than the repair would cost.
Fixing a car before selling it is only worth it when the repair is cheap and visible, or when it is legally required to complete the sale. Expensive mechanical work usually costs more than it adds to your sale price, so the smarter move is to check what the RMV requires, fix the small obvious things, and let the price reflect anything bigger.
It depends on what's broken. Anything that stops the RMV transfer going through — an expired revenue licence, an expired VET certificate, or no valid insurance — has to be sorted before or during the sale, so that isn't really optional. Beyond that, the rule of thumb is: fix it if the repair cost is clearly less than the price drop a buyer would demand for leaving it broken, and skip it if the repair cost is close to or more than that price drop.
A buyer who sees a badly scratched bumper will usually knock off more than the cost of a respray touch-up on that one panel. A buyer who finds a tired automatic gearbox will often knock off less than a full gearbox overhaul would cost you, because they know they're buying a used car with used-car problems. Compare your car's likely resale value on /price-check against mechanic quotes before deciding either way.
Small, visible, cheap-to-fix issues almost always pay for themselves. This includes a cracked or chipped windscreen, broken or hazy headlight lenses, a dead battery, worn-out wiper blades, missing wheel caps or a flat tyre, torn seat covers, and a dirty engine bay. These are the first things a buyer notices in person and in photos, and they make the whole car look neglected even if the mechanicals are fine. A proper valet, a service with receipts, and clearing any dashboard warning lights (like a check-engine light caused by a loose fuel cap or a worn sensor) also tend to be worth the modest cost, because they reassure a buyer that the car has been looked after.
Expensive structural or major mechanical work rarely pays off before a sale. This includes a full engine rebuild, gearbox replacement, hybrid battery replacement, full re-upholstery, or a complete respray. These jobs cost a lot, and buyers shopping for a used vehicle already price in some wear and tear — they are not expecting a brand-new car. If your car needs one of these big-ticket repairs, it is usually cheaper and faster to be upfront about the fault, get an independent quote so you can show the buyer the real cost, and let that amount come off your asking price instead of paying for the repair yourself. You can see how similar vehicles with disclosed faults are priced by browsing comparable listings on /vehicles.
Yes — a short paid inspection removes most of the guesswork. A trusted mechanic, or a mobile vehicle-inspection service that checks the engine, suspension, brakes, body and (for hybrids) the battery, will usually find the same faults a buyer's own inspector would find. Independent inspection services in Sri Lanka report checking well over 100 points on a car, covering accident and structural damage, the engine and hybrid system, suspension, transmission, brakes and the exhaust system (greasemonkeyinspectors.lk). Paying for this once, before you list the car, tells you exactly what to fix, what to disclose, and what to leave alone — instead of being surprised by a buyer's mechanic during a viewing.
Sorting out your paperwork often matters more to the sale going through than any repair. Before you advertise, check that your revenue licence is current, that your VET certificate (where applicable) hasn't lapsed, and that you have at least third-party insurance in place — all three are checked at the RMV counter during ownership transfer, and a lapsed one can delay or block the sale even if the car itself is in perfect condition. If your revenue licence has expired, you will need an in-date VET certificate before you can renew it, so build that time and cost into your plan if you're selling soon. These compliance costs are separate from, and usually smaller than, mechanical repairs — but skipping them can stall a sale that's otherwise ready to close.
If you're unsure whether a specific fault is worth fixing — a knocking noise, an AC that only works sometimes, or a hybrid battery warning — ask in the /forum, where other sellers and buyers in Sri Lanka share what they paid for similar repairs and what buyers actually accepted. When you're ready to list the car, you can post your ad on /post-ad, and if you're meeting buyers for viewings or test drives, follow the precautions on /safety-tips.
When a buyer pays through a lease or bank loan, their finance company sends an approved valuer to inspect your car and registers itself as absolute owner on the CR book before you get paid, so expect extra paperwork and a short delay versus a cash sale.

The safest payment is a bank transfer or bank draft you verify yourself by checking your own banking app or calling your bank — never a screenshot the buyer sends you. Don't hand over the CR book, keys or signed MTA 6 form until the money has actually settled in your account.

Yes — the DMT's ownership-transfer system checks that your vehicle's VET (emission test) certificate and revenue licence are both in date before it lets the transfer go through, so renew an expired VET before you sell, unless your vehicle is exempt.
