2005-reg Diesel, Owner for 1 to 3 years

Despite being a low mileage and well cared for car, the turbo charger failed costing over ł1500 to repair. the only problem with the turbo was aseized actuator arm which could probably have been frred off with an overnight soaking with lubrication. although the actuator could have been detacheed from the turbo, the item was only supplied complete with the turbo. the mechanic stated that the turbo (my old one) would be serviced and put back on sale at the same price that I paid. Although I do not drive my car hard, I expected better economy from a diesel. The performance from mthe engine is very good, particularly the mid-range power.

Excellent car to drive, great handling, comfortable and engine pulls well in all gears. High build quality internally and externally, very desirable but yet still has very reasonable running costs. Plenty of room for the driver and front passenger, rear seats only offer just adequate space for 2 adults to travel comfortably, boot is relatively small for the class (worth it for rear wheel drive driving experience and balance), plenty of space if you need it with rear seats folded down. Love the car.

Fantasticly fun little car, mean straight-line performance as well as through corners. The diesel engine ensures it performs on the fuel economy side too. I was surprised when one morning it let me down on the M1 however a BMW engineer soon came out and when he couldn't resolve the issue on site he resolutely escorted me to the nearest dealer. To sum it up: a brilliant drivers' car however you don't expect a >£1k bill on a car that of its age so perhaps a little unreliable.

We had a manager leave and I ended up with the car. The 1 series had such good reports I was sure it would be a good car. Nothing but niggles electric windows stopped working last week in the snow, so did the mirror dip this started to work again yesterday.

Some of the problems stem from the previous user of the car.

Worst of all the snow and rear wheel drive. I will never own a rear wheel drive car again.

Give me my Altea any day over the BM.

Bough as ex demo in march 2007 after it was registered in sept 2006. had no reliability issues. nothing has failed. 6 speed gear box. cruises well. I only use the car for leisure trips and holidays 3 times a year. serviced at bmw main dealership every 2 years due to low annual mileage. satisfied with this arrangement.

It is reliable but very bad in snow being a rear wheel drive. Service charges are high at dealer ship they rip you off but not very costly if one goes to a reliable service garage, and the parts have to be replaced on which ever parts gets needs replacing and are more or less same as the other makes.

Has never let me down. (oh dear bet that's torn it!). As a skilled mechanic I do my own servicing. bmw dealers are far too dear. parts are easily available and straightforwrd to fit. for a 2litre engine fuel consumption is excellent and even better on the later models.

Great to drive, efficency dynamics engine delivers good performance and excellent fuel consumption. Owned for 18 months and returned to dealer twice for minor problems. Good styling, performance and praccticality would definately choose a 1 Series again in the future.

2010-reg Petrol, Owner for 1 to 3 years

Generally reliable but needed all ignition coils replacing under warranty as well as an engine sensor. Very economical for a 2.0 petrol engine, low servicing costs but only average road tax and insurance costs. Just the right amount of power for everyday road use.

Not a family car --really for two people only ---
Car very reliable running costs reasonable --paintwork excellent
Run flat tyres give a harder ride and create some road noise
Only critical point would be that the seats should have a better height adjustment

No reliability problems. engine seems bullet proof. Very fuel efficient, however consumables such as brakes (pads / discs) are very expensive to replace and labour rates at bmw are ridiculous.

Brilliant but small car - but no surprises there. Disappointed by the stock levels (or lack of) of run flat tyres in the area when I had a puncture but this isn't BMW's fault.

Can't fault it in the time I've had it it's not put a foot (wheel?) wrong! It's a company car, fuel consumption's the only bill I have to worry about and it's not too bad.
