Hry all, looking into getting a new car next year, my current one is doing my head in. Current car is a 3door Mk4 2.0

Current ideas would be:

1.8 4 door MK4
1.7 CDTI MK5
Maybe a corsa D at a push but Im not a huge fan of these...

Anyone have any ideas on a decent car under a 1.8 and around the 4-5k mark?
