The BMW 3 Series is still one of the best used executive cars out there, and a superb all-rounder. It might seem like BMW has every niche covered in the motoring world these days, but if there's just one car that's come to define the German firm's products it must be the BMW 3 Series. The petrol range consist of a 2.0-litre 181bhp 320i, a 242bhp 328i and 248bhp 330i, with the high-performance, 3.0-litre six-cylinder 302bhp 335i and 321bhp 340i versions completing the lineup. There are four major trim levels on offer: ES, SE, Sport and M Sport. ES has 17in alloy wheels, climate control, a DAB radio, Bluetooth, cruise control and a 6.5in infotainment screen. Go for SE to get auto wipers and lights, rear parking sensors and dual-zone climate control. Sport grade adds numerous sporty touches including lots of red trim inside; some gloss black exterior trim and sports seats. M Sport adds firmer suspension, larger 18in wheels, and a more aggressive bodykit outside. On the road, every 3 Series model performs with an all-round competence that will always place it at or very near the top of their particular class. Most engines combine power and economy in almost unmatched excellence and add a dollop of refinement to the mix. All versions handle beautifully, and the steering is still superior to that of any rival. Inside is an interior that makes much use of high-quality materials, and fits form to function neatly while offering ergonomic efficiency in its major and minor controls. Probably one of the best cars to drive with its perfect 50/50 weight distribution. Opt for German engineering for a perfect car.
