Working at a friends mechanic shop for a few days a couple of weeks ago and we had this happen, it was all quite funny and I've just gotten off the phone with him now.
A lady came in with a 2002 Tarago for a knocking sound in the engine.
When we got in the car to drive it onto the hoist we noticed there was no last service sticker on the window, which we though was odd but you know it happens.
Checking the log books, this lady had brought the car new, straight off the lot and has had it ever since. She got the free complimentary 1000km service and tune up as you get with most cars. After that there is not one entry in the log book, I'm starting to get worried.
Luckily the lady was still waiting for her husband to pick her up and we asked her when was the last service, you know maybe the partner does them at home. She validated our disgust and fear, this car had not been serviced for 179,000km. Not even kidding you guys, and it was still running!
My mate said he would do the service but made no guarantees.
After the service the car was running, and the knock had mostly disappeared, so happy customer.
A week later she called up, engine is blown.
She comes into the shop and hurls abuse and all sorts. As my mate is trying to explain to this ignorant fwit that the 179,000km before hand traveled on the engine without a service is what caused her engine to blow, not the fact that we serviced it.
Ends up walking away 8k out of pocket for a new motor and then fitting.
As she was paying the bill, she said.
'I knew I shouldn't of got my car serviced'
I honestly don't think she will get this new engine serviced either.
But doing some math I actually think shes come out on top here. Say she got it serviced everything 5000k at $200 a service. That would be around 36 services over its 180,000k life time if all that was ever done is oil + filter. 36 x 200 is $7200 worth of servicing. That dosen't include any other major parts or engine work. So honestly, after everything, I think the $8000 engine fitting would've still left her in front on the $$ side of things.
The ignorance of some people...
