|---|---|---|---|
| Engine: | 3.0 Diesel | 1.9 Diesel | |
| Camshaft drive: | Timing chain | Timing belt | |
| Engine chain usually needs to be replaced less often than the timing belt, but the cost of replacing the chain is usually higher. Chain motors are considered to be more reliable, but noisier and more vibration generating. | |||

Drive type | |||
| Wheel drive type: | Rear wheel drive (RWD) | Front wheel drive (FWD) | |
| Front-wheel drive cars (Opel Astra) have better traction on slippery roads and when climbing hills, better fuel economy, and are less expensive to purchase. On the disadvantage side, FWD cars usually have less towing capacity, poorer acceleration and harder handling. Rear-wheel drive cars (BMW 3 series) have better handling on dry roads, better acceleration, more even weight distribution and more fun to drive. RWD is also better for towing large loads. The cons of rear-wheel drive are less interior and trunk space and more difficulty maneuvering in wet and snowy conditions. | |||
| Ground clearance: | 143 mm (5.6 inches) | 122 mm (4.8 inches) | |
| Because of the higher ground clearance, BMW 3 series can perform better on bad roads - it can go over higher obstacles and bumps. At the same time, the higher ground clearance can reduce stability and handling on paved roads, especially at higher speeds. Note, however, that this BMW 3 series version does not have 4x4 drive, which is very important in poor road conditions. | |||

| In general, the longer and for more car models an engine is produced, the better its serviceability and availability of spare parts. BMW 3 series might be a better choice in this respect. | |||
