Newer Toyota autoboxes are not good.
Avensis petrol estates are good cars. I’ve had several, older pre- and post 2002? Shapes. The older you go, the worse underside corrosion will be, although the further south the car has spent it’s life, the better. They are workmanlike cars of acceptable (but not Volvo/Saab) comfort.
You could get something nice for 2k
Old civics post 2006 are spacious with the rear seats down as mentioned and are decent but I prefer estates if you can get away with them
^ belt change on pre 2008? Diesels is important as they go eary. Post 2008 are chain driven I believe
