Hey Hey

I am in Australia and am looking at buying my first Mercedes but due to me wanting to cut my car loan considerably i only want to spend around $15,000 (AUD). I currently own a 2000 Audi A6 2.8 Quattro. I LOVE the car but it has given me A LOT of trouble and cost me about $10,000 (just in repairs) over a year, however i cannot bear to not have another european car.

My question is, what is a good reliable model Benz for me in my budget? I know i dont have much money to spend and it will be an older model however i just LOVE Mercedes Benz and really want to get into the family! :P

Any suggestions (except for an A-Class) are more than welcome!

Thanking you
