Vinman,
Purchase the 1/48 Tamiya Bf109E-3, its a great kit with great fitting, but remember, do not remove the seam on top and bottom of the fuselage, it existed on real aircrafts so do not remove it. You can also purchase the right size of seat, exhaust pipes, and propeller blades with spinner at www.ultracast.com, trust me, those products are more accurate if you want a realistic look of your aircraft.
