Where to Find Car Parts: Best and Cheapest Sites
Quick Answer
The best places to find car parts are online parts retailers with a registration or VIN lookup for routine items like filters, brake pads and bulbs, dealer parts departments for exact original parts, local parts shops for same-day jobs, and breakers or salvage yards for cheap used body panels and trim. For the lowest price, find the correct part number first, then compare it across several sites including delivery and return costs.
Key Takeaways
- Searching by registration plate or VIN avoids most wrong-part orders.
- Copying the part number from the old part lets you compare prices across sites fairly.
- OE-quality aftermarket parts are often made to the same spec as originals for less money.
- Used parts suit body panels, mirrors and trim, but not brakes, steering or airbag components.
- Some parts carry a refundable deposit (core charge) when you return the old one.
Where to Find Car Parts Compared
Each type of seller has strengths, and the cheapest option for a door mirror is rarely the cheapest for brake discs. This table shows where each one shines.
| Seller type | Strengths | Weak spots | Best for |
|---|---|---|---|
| Online parts retailers | Low prices, plate or VIN lookup, home delivery | Waiting for delivery, returns by post | Servicing parts, brakes, bulbs |
| Dealer parts departments | Exact original parts, expert advice | Highest prices | Electronics, keys, model-specific parts |
| Local parts shops | Same-day collection, staff help | Higher prices than online | Urgent repairs, batteries |
| Online marketplaces | Huge choice, competitive prices | Quality and fitment vary | Accessories, trim, older cars |
| Breakers and salvage yards | Very cheap used parts | Wear, limited warranty | Body panels, lights, interior parts |
How to Get the Cheapest Car Parts
- Find the exact part number from your handbook, the old part or a VIN lookup.
- Compare that number across three or more sites, including delivery.
- Check the warranty and return policy, especially for electrical parts.
- Look for multi-buy deals on servicing parts like filters and plugs.
- Consider used for cosmetic parts, and new for anything safety-related.

OEM, Aftermarket or Used?
Original (OEM) car parts are made by or for the car maker and fit exactly, which matters most for sensors, electronics and complex engine parts. Aftermarket parts range from budget to premium, and good ones match or beat the originals for things like brake pads, filters and wiper blades. Used parts are a great way to save money on cosmetic items, but buy them only from sellers who describe their condition clearly.
- New OEM or quality aftermarket: brakes, tyres, steering, suspension.
- Aftermarket is fine: filters, wipers, bulbs, batteries.
- Used can work: doors, bumpers, mirrors, interior trim.
What to Expect at Each Price
| Price (USD) | Typical parts | Notes |
|---|---|---|
| Under $30 | Bulbs, wiper blades, filters, fuses | Easy DIY replacements |
| $30 to $100 | Brake pads, batteries, sensors, mirrors | Compare prices carefully |
| $100 to $400 | Brake discs and pads sets, alternators, headlight units | Check warranty and fitment |
| $400 and up | Clutches, turbos, major engine and gearbox parts | Get professional advice first |
Most savings on car parts come from comparing the same part number across several sites, and the difference on routine items like brake pads and filters is often bigger than people expect, especially once delivery is included.
Safety Notes
Brakes, steering, suspension and airbag systems are safety-critical, so have them fitted by a qualified mechanic unless you have the right tools, torque settings and experience. Never buy used airbags or seatbelts. Check that replacement lights, including LED upgrades, are legal for road use where you live, and always test brakes and lights before driving normally after any repair.

Our Recommendation
To find car parts at the best price, look up the exact part number first, then compare online retailers, local shops and dealers, using breakers for cosmetic items. Pay a little more for new, quality parts on anything safety-related, and leave brakes and steering to a qualified mechanic if you're unsure.
