Check out one of these cars listed below. They all have the legendary SR20 motor. For your specific needs, I would recommend the 1999 Sentra SE-L, also known as the Sentra SE-Limited. It was only made in 1999 and is the only new-ish Sentra with a good SR20 motor. It's also the best looking Sentra ever, IMO. The 95-98 200sx SE-R will be the most fun car you can get for your needs. It's not too old, performs well, and has proven reliability. All Sentra's and 200SX's from 91-99 have been proven as the most reliable cars to come out of Nissan, beat out only by the 89-94 Maximas.

For a huge increase in power and, amazingly, better gas mileage too, get an SR20 car and have your local tuning shop replace the SR20DE(the motor that's in the car), with a Japanese SR20VE. You'll go from 140hp to nearly 200hp and improve your gas mileage by at least 3-4 mpgs.
