The worst car I owned was a 1981 Nissan Bluebird LX.
Touted as the worlds first 4 cylinder limo. Oh it was luxurious....velour trim and electric windows.
But the body was so heavy, it should really have had a V8 under the bonnet.
Show it a steepish hill and it would start to sob. I'd have to knock it down to first gear and let it take it's own sweet time, mean while the traffic would build up behind you.
The best car I've owned were a 1974 Toyota Corolla...it just kept on keeping on. If the body hadn't fell apart with rust, I'd still be driving it today.
It trekked from Sydney to Brisbane too many times to count and never overheated once.
I traded it in on the Bluebird.
Oh, I love the little Kia Cerato I have now.
