^oh wow....
i like it around 27-29,summer gets intense here,up to 40.. But good thunderstorms every afternoon.coldest we get in peak ofwinter is 7/8degrees C.and we all winge about that..
What u doing with your car?? Is it misbehaving.
I still have to do conversions for those temps

27-29C is 80-85F, which is right around where I like it as well. I dunno about the humidity down under, but in the spring and summer here it gets really really humid, with heat index going into the 90s and 100s even when the temp is in the low 80s. So it really is the humidity that sucks the life out of you, I like it though, for whatever reason...
7-8 degrees C is...44-46F, which is about right for the winter days here, during the night time it can get to the 20s or 30s F...which is -6C to 0C. So a bit colder
I hate the cold too though.
As far as my car goes, its always misbehaving, its a '95 Ford four-door sedan, called the Contour here, but called the Mondeo in the UK, Europe and I
think in Australia it is/was called the Mondeo as well. Like most Fords (at least U.S. Fords, I dunno if Aussie Fords are better or worse) it has developed strange characteristics and quirks, but it refuses to die and has lasted forever, despite me beating the crap out of it...I drive really hard and fast, and I drive every car I've driven hard and fast. It's got just over 177,000 miles on it. Wait, do y'all use kilometers of miles in Aus.? Either way, that's about 285,000 km...if you all even use kilometers. I don't even know which countries use miles and kilometers come to think of it. Anyway, that's a good amount of miles and it's still on all original engine/transmission/clutch parts. Some of the body and interior had been replaced, but with junkyard-sourced cheap parts only.
Either way, its expected for American cars to last 100,000 to 150,000 miles and Japanese cars to last a bit longer, at least cars of that vintage. This is the longest my family has had a car last, except for my Dad's old 1978 Chevrolet Caprice (I believe that's a Holden Caprice for you all) that lasted FOREVER. The only reason we got rid of it was because it's 305CID/5.0L V8 engine got like 10 miles per gallon on a good day.
I don't know why people hate on American cars so much, in the late 80s and early 90s they were much worse, but now they're just as good, if not better than, Japanese cars as far as reliability and cost of ownership. I actually think its cheaper than owning a Toyota or Honda because I can (and do) get all my replacement parts from junkyards.
