2006 Nissan Sentra Sedan 1.8 S 4dr Sedan (1.8L 4cyl 5M)
Best gas mileage car ever!!
 This is my 3rd Nissan Sentra. The first 2 lasted 240k and 320k. This one is heading for 400k if the body will hold. With the 1.8L engine, manual 5 spd transmission, Amsoil 0w-30 full synthetic oil, full synthetic in both the manual transmission and the transaxle, this car averages 38-44mpg with cruise control on and at 65 mph. I use my Garmin Nuvi to sync my speedometer and find it is 3mph slow. Bad points: Slow acceleration Good points: Great in the snow, even in WNY winters. Very reliable. Only dealer service I have had is having the belts (timing, alternator, water pump) changed every 60k. Oil changes at 10-15K miles using Amsoil filters.
