OK sana kung makakahanap ka ng Vios which is in good condition for this price. Pero kung yung pinakabase model lang ang makukuha at yung pinakauunang batch pa, I'd rather get something else. As for the EK Civic, I think your budget can fetch you the post facelift late '98-2000 model already. The looks are really sporty and timeless, IMO. You get excellent performance and gas mileage and its not cramped like the Vios. Just make sure the one you get was not heavily modified or raced. As for the AE101 Corolla, why if I can afford to get a post facelift EK, why would I bother with the older Corolla? The Corolla is a good car, its just that its a bit old. But if you should insist with it, the top of the line 1.6GLi fits your budget, no need to stay with the carbureted XE which is both weak and quite thirsty (as compared to newer DOHC 16 valve EFI 1.3L engines).

AFAIK the Civic LXi uses a 1.5L 16 valve EFI non-VTEC engine good for 105hp and 138Nm while the Civic VTi uses a 1.6L VTEC engine good for 125hp and 148Nm. I'd definitely get the VTi to go with the excellent handling and so that I can have fuel efficiency and also the power when I want it.
