"Wannabe test pilots can forget about contacting me; no one will test drive this car until your payment is safe and sound in my bank account. (Its only insured for me driving it). If you want to test drive one of these powerhouses, go and see a Kia dealer; and get a quote on a new one whilst you're there

."
If I were in Australia, that would be a deal-breaker right there. Who in their right mind would buy a used car without test driving it unless it's a garage queen like a ZL-1 Corvette (only two made) or Vector W2 (only 20 made)?
"No test drives" usually translates to "I really fraked up this car big time" -- like 99.9999% of the time.
You took a huge risk buying that thing... I'm glad it worked out for you.
