The guy sounds really dodgy about the car

1. He won't let me take it to my mechanic for a check
2. He won't let me get an RACV inspection
3. He refuses to get a RWC
4. He wouldn't give me his landline #
5. He said it was insured for $13,000 then he said it wasn't insured at all
6. Has new plates because he took off his personalised ones (could be true)
7. He's asking $9000 but said he would take $7500
8. He needs to get rid of it by Friday morning

Very dodgy indeed. Oh well, keep looking for others i suppose
