Back seat is very small..

Car is awesome, no dislikes. Color & interior are top notch & durable materials. I love BMW because they are amongst the safest.

The car is one of the safest on the road & is a fast 2 door coupe.

It's a black BMW. It is low & sporty. It has navigation & is very fast.

Great looking car but has a reputation for expensive ownership.

Like the way this car looks & drives & performs but it is has several problems including the convertible top that gets stuck. . . Or the sensor malfunctions causing the warning lights to come on. To service the vehicle is extremely expensive & I have run into situations that the dealership has difficulty resolving.

Negative Owner Reviews

Ren R

Not too reliable. Not going to keep.

I have to make a good effort to keep my car running, I am not sure why but something is wrong every other week with it, I make a constant effort to watch and make sure it runs well. I am going to replace it soon and make sure that the car is functional for a new buyer.
