Bike rack for three bikes (one adult two kids) that will fit a hatchback?

[notquitesureagain]

Bit baffled by all the (sometimes conflicting) information coming up in my online searches - anyone got a good bike rack that fits the description above and is nice and easy to fit/use.

The kids bikes are both 20".

Thanks v much for your help

I recommend this site. We have a tow bar carrier - but we take the bikes out most weekends and it was worth it for us. Bought it through them and very pleased with service.

thanks haggisaggis - will have a look now
