I think it has the same engine that they put in the Audi's of that vintage, I know the earlier versions of that engine were prone to head gasket failure, not sure if they had the problems fixed by that time or not. Gas mileage should be in the low 20s for the city/highway. The horsepower rating is somewhere around 180.
