I bought a car from Central West Motors on the 16th of July. The aircon and stereo was not working at this point so they said that the fuse or something needs replacements and to bring it back the next week. As I needed the car and because it was not affecting my driving, I took it. I drove it for less than an hour and the engine light came on. The car salesman told me to drive it for the weekend and then bring it in as originally planned. So I took it back on Monday 18th July. The car salesman drove it around with me in it and then said it was driving poorly, so they will get it fixed and mentioned it is probably the coils and spark plugs. They got some secondhand parts and replaced it and I got the car back on Monday the 25th of July. While driving it back home that night, the engine light came on again. I emailed the dealers that night and rung and spoke to the car salesman the next day. I stopped driving the vehicle and left it in my garage till I could take it back to him. He was going to talk to his boss and work out what to do as at this point, I told him I would like my money back as it is a lemon car. He then rung me on Wednesday and said his boss was so disappointed in his mechanics and he would like the car to go to Holden directly to get fixed and to drop it off at the car yard so they can send it to Holden. I dropped the car off on Thursday 28th July. Holden told them the Catalytic converters need replacement and sent it back to them. Today is the 5th of August and I still have not had my car back. I rung the car salesman just before and he said he will arrange for a courtesy car tomorrow as they have just sold 20 cars in the last week and it has been busy. I am unsure how this is my problem as throughout this whole process, their one-month dealer warranty has been ticking away and I have only driven this car for 2 hours. Could I get my money back?
