as for common, it's a H not a 2H, so parts are a bit harder to find

always do things the hard way
ok, rang around, found that 4 core would cost me 450, 3 core was quoted as 350, from the same place i was bitching about.
took it in for the 3 core (knew it was a bad idea) and said that if possible i needed it the next day for a trip, which was true, and he said no worries... so i got it back 5pm the day after i said i needed it. no contact to tell me it was taking longer
so i rock up, hand over my $350 and say cherio, didn't even look at the receipt. he's like, "your short changing me".
so i look at the receipt, and low and behold his $350 flat out quote was not what he was charging me. cost $60 for labour/ workshop charges (which he should have told me about) and $41 GST tax. which legally must be included in the initial quote. so my 3 core cost more than a 4 core, which i could have had done a day before.
dad started to kick up a fuss, saying he had to quote me all charges, and that we should get it for his initial quote of $350. the guys said he'd take our cash, and the radiator, and we could sort it out after the long weekend... so we couldn't go away camping. so we paid.
and that was a NATRAD service, a national radiator chain in australia. at least the 3 core coped with 40degree celsius heat....
