A lot of city users don't travel very far, so it is quite possible for a 98 to have only 69,000 km.

I don't really like either as a secondhand choice, but the Vectra is a good looking and powerful car, and possibly the better choice of the two... baka nga lang mang-aray ka sa gas, coming from a 1.5.

How about an Altima? Good engine on that one.

Not considering any 1.4 - 1.6 compacts? The Sentra/Civic/Lancer/Lynx/Corolla/etcetera are all a size up on the Lynx and won't eat up your gas budget (as long as you get an MT) unduly.
