OnlineAuto.com.au
OnlineAuto.com.au says it'll help you find the right car, thanks to its "bulk buying power", which appears to be based on fleet pricing. It also puts a big emphasis on helping you pick the right car, with example savings for different models. You can handily search for cars based on features and specs, like seat numbers, room for tall people and even how the exhaust sounds.
The site allows you to fill out a quote form, which we tried out. It's a pretty brief and straightforward process: once you've selected the model, you punch in some contact details. OnlineAuto.com.au also asks about your purchasing timeframe and whether you've yet test-driven or found the exact car you're after.
Average OnlineAuto.com.au savings: $4,104*
Once you've sent your request off, a specialist from OnlineAuto.com.au will ring you. Finally, after 48 hours, you should receive offers from dealers Australia-wide. According to its site, OnlineAuto.com.au can also help you organise a test drive, apparently for more than one vehicle. Finally, it promises to arrange delivery of the car you purchase.
It also accommodates trade-ins and valuations with a pick-up service. Those could help take some of the hassle out of getting rid of your old car.
*OnlineAuto.com.au added together the savings of cars purchased using its service between 1/01/2017 and 5/07/2019 (a total of 2,625 customers). The total savings amounted to $12,117,142.87.

Carma
Carma boasts a way to buy a "quality used car without having to trust randoms you've just met".
You can browse hundreds of used cars on the Carma website by filtering for various specifications such as car make and model, price, transmission and fuel type. You're then able to inspect the car in the virtual showroom, which offers a 360° view of both the interior and exterior of the vehicle.
All the cars available have been road-tested, inspected and reconditioned to ensure the best quality.
Once you've found your perfect used car, you can either fill in the form online to purchase the car outright or you can apply for finance through one of Carma's lending partners. You can also call Carma to walk through the forms with a representative. If you're in the Greater Sydney area, Carma will arrange to deliver the vehicle to your door once payment or the finance plan is finalised.
Unlike if you were to buy through an independent seller, Carma offers a 7day money back guarantee, a 3 month warranty and 1 year roadside assistance.
