Yep i got my car from Melville Autos too.
Kevin (older guy) was pretty good, as the rest have said he will still look after you after he sold you the car. I got one of the MkIII's in question as he had a heap at the time and you could see he wanted to get rid of a few before the import laws came in. He threw in a alarm, and gave me a few hundred off.
I had a brake and shock problem when i took it home and he was happy(well kinda) to fix it and now its good as new. No problems with it yet and i have done like 10,000ks on it.
