best to ask whats your main goal from a 4 cyl car .. economy or fun - ?
then start from there
St162 celica - the one you mentioned is a good start for both, and are Ok as autos - not totally gutless.
outside fo that - next best bet is a 4ag twin cam corolla ( ae82 , or 92 - seca too ) Cheap and cheerful - easy to maintain but most are manuals. The autos will Struggle for " go "
if you want something less pokey but more comfortable again - An st184 Celicas a good choice .. a little higher in price - but they have all the mod cons..
if you just want a run around thats reliable - auto and slightly bigger - the camrys a good buy - but will use a bit more fuel because of its size..
Seriously though =- for the best toyotas out there - you may need to look at a manual to get the best benifits from the engines the above have .. Autos Sap ALOT of power , from a 4 cyl.
If your stuck on autos - look maybe into something like late eighties 7mge Cressida - VERY nice cars - still pokey enough , and auto's are plentiful. They are a 6 cyl though.
