Early Civic specs were be erratic:
S trim had four electric windows but no radio(?)
SE added radio/CD and climate control (plus 16" alloys on 1.8/2.2)
Sport had HID lights and 17" alloys, some also had front fogs and leather steering wheel.
ES added cruise, dual zone climate, leather steering wheel, panoramic glassroof but had 16" alloys and no HID lights.
EX was an amalgamation of Sport & ES specs plus sat nav and bluetooth but minus the glassroof, although I think was available as an option for a short while.
No USB or even AUX until facelift (starting on 09-plate), even though the Mk1 Jazz had the latter at the time (

?).
Some overlap between pre- and post-facelift due to the downturn in the economy.
No DPF on the diesel but they do have DMFs, clutches can have a short life.
Service bulletin for the sticking fuel cap should be sorted by now.
Paint said to be thin, and I think there was some minor issues with rust under the door seals?
Rear suspension creaks, some owners had springs and/or dampers changed regularly under warranty.

Which Mazda3 are you looking at? 04-09 cars can have issues with rust. '09-'13 in my opinion are very underrated and I considered replacing my Jazz with a used 2.0-litre petrol Sport back in 2012...if I could actually find one! Not sure if they fit in your budget.
The 1.6-litre petrol is rather underpowered, only a little over 100bhp.
The 1.6-litre diesel is PSA Peugeot-Citroen sourced, not sure where the 2.2 diesel comes from - these have well documented DPF problems so best look elsewhere.
The BMW 1-series is very tight in the back, '07 facelift cars are said to be better made and were one of the first cars on the market to have stop-start before other makers followed. I always had a soft spot for 1-series coupe.

I can't comment about the Focus or Astra or Auris.
