Fully rebuilt M20B23 – 12,000 km of reliable use
Professionally rebuilt M20B23 engine, approximately 12,000 km driven since rebuild, with extensive documented investment. Total vehicle mileage unknown.
1984 BMW 323i (E30), early two-door six-cylinder model, located in Lisbon, Portugal.
The 2.3-litre M20B23 engine was professionally rebuilt in January 2025, when the non-original instrument cluster showed approximately 10,000 km. The instrument cluster was already fitted before the current ownership and showed approximately 2,500 km when the car was acquired. No reliable record of the vehicle’s total lifetime mileage was supplied, so the true total mileage is unknown.
Since the engine rebuild, the car has covered approximately 12,000 km in regular and long-distance use and has proved fully reliable.
The car has benefited from extensive documented investment, including a €7,260 mechanical rebuild and refurbishment programme, together with €5,200 invested in a pair of brand-new RECARO Classic LX ergonomic seats with adjustable lumbar support.
Further improvements include Bilstein dampers, new original BMW springs, restored original BMW alloy wheels, four Hankook tyres, an Alpine UTE-200BT head unit and two JBL Stage 161F rear speakers.

It has always been garage-kept but is regularly driven and enjoyed. It is not a static showpiece: the approximately 12,000 km completed since the engine rebuild demonstrate that the car is dependable, usable and ready for long-distance driving.
