Have a look at the Safe n Sound Compaq (they have a Compaq Deluxe too). It's designed for smaller cars (such as hatchbacks), it's convertible (birth to 18kgs), it ranked number one in Australia for safety and usability last month (owner of a babyshop showed me the report she received) and it's well priced - about $300 for memory (the deluxe model is a bit more). We don't need a compact car seat but I'm actually considering getting it for our first bubs due to reviews it receives and of course the recent ratings for safety.
