The Lynx matic is pretty bad... though I don't have firsthand numbers, some people get dismal numbers, around 6 km/l or so... but some people also get dismal numbers with the 323.

As to whether it's quieter than the Lancer... I don't think so. The road noise on the Lynx is actually pretty bad... but it depends on the tires. Medyo de-lata yung sound ng doors, din. It's a wonderful car to drive, but if you're looking for quiet, you might want to look elsewhere. Still... it's a good car, despite the lack of wheel-well insulation.

The Avanza? Foam and rubber lang katapat nun...
