The BMW 323is (chassis code: E36) is a very reliable automobile with exceptional fuel-sipping properties. Naturally you'll have to replace some parts along the way, however they are not as expensive as most would have you believe. Most repairs can be done by even the most novice of home mechanics. The cooling system should be overhauled every 60-80k miles but even with OEM parts the whole task should cost the DIYer no more than $350-400 (radiator, thermostat, water pump, hoses, etc.). The engine is brilliant and I still see 27 MPG as my overall avg. As mentioned in the title, I am currently at 210,000 miles and still on the factory clutch! I will keep this car for at least another 100k.
How it drives and the sound of the inline-6 engine.
