Roadworthy and repairs, Landcruiser

Provided a RWC and repairs for my Landcruiser. Gave me several cost options and were excellent in communication. Unfortunately there was an issue which was outside their control, that I picked up later, however they went above and beyond to resolve it... just outstanding customer service. VERY honest business that you can trust.

Thornlie, street by street

Estates from three decades

The Thornlie estate was subdivided after 1954, Crestwood began in the early 1970s as a planned estate, and Castle Glen and Forest Lakes came in the 1980s. Blocks are often 700 to 900 square metres, which tends to leave room in the driveway for a mobile service.

Albany Highway into town

Albany Highway is the road to the CBD. Through Maddington, Gosnells and the other south-eastern suburbs it's shopping strips and traffic lights, the sort of crawl that wears brake pads and keeps an engine idling through a February afternoon.

Roe Highway and the trucks

Roe Highway is a key heavy vehicle route around Perth's outer suburbs, running west to the Kwinana Freeway at Bibra Lake. If that's your daily run, the car piles up kilometres, and its service can come due on distance well before the date in the book.

Trains both ways since 2025

Thornlie station opened on 7 August 2005 at the end of a branch line. On 8 June 2025 the line was extended through Nicholson Road and Ranford Road to Cockburn Central, so a train from here now runs across to Cockburn as well as into the city.

The licence

A Thornlie business that services cars needs WA's repair business licence, and the people working on your car hold a repairer's certificate. Consumer Protection WA says to run the online licence check before you go ahead.

Which service does a Thornlie car need?

Many service books list two schedules: one for gentle driving, and a tougher one for short trips, heavy traffic, heat and towing. A car that does Albany Highway at peak hour through a Perth summer may well belong on the tougher one. Ask the mechanic to check the book and say which applies, and why.

Before the work starts, get a quote that sets out the job and its cost, and ask to be rung before anything extra is done. Consumer Protection WA suggests asking for an itemised list of the work when you pay, and keeping it with the receipt and the stamped book.

Under a new car warranty? A qualified independent mechanic servicing a Thornlie car to the maker's schedule and specifications doesn't, by itself, void that warranty. Car service in Perth goes through the service itself, and logbook servicing explains what the book asks for.

Parking at the station in summer

If you drive to Thornlie station and leave the car in the sun all day, the cabin and the battery cook. RAC WA suggests a sunshade to cut the heat build-up, and checking the battery as the weather warms. A slow crank on a hot afternoon is the early sign: car batteries in Perth covers what happens next.

If it were our car

We'd look up what the book says is due at the current kilometres, then ask for the service in writing before handing over the keys. If the car did the Albany Highway crawl most days, we'd ask about the harder-use schedule, and we'd have the battery and coolant looked at before December.

Questions people ask

Can a mobile mechanic service my car in Thornlie?

Yes, for many routine services, as long as there's a flat, safe spot to work, and Thornlie's bigger blocks often have one. Pick "Come to me" in the card. A job that needs a hoist goes to a workshop.
