what is the difference between a497 and a400?
also what is the life expentency for 1.8t engine ? 160,000?

RE: what is the difference
 

97 has a different trim pieces inside, diferent headlights, tails, and is n-dbw, 00 is dbw and has the 1pc headlights, updated tails, different stereo setup. Af far as life expectancy of 160k, it has been well maintained, than it should run for a long time, but gotta realize when mileage is that high something can just decide to fail with no warning.

DBW=Drive by wire; which basically means that the computer controls the throttle body
You can put the updated headlights and tailights in but you will need to do some modification to make them fit.
