Faults:

Car was supplied with one wrong size tyre.

Cigar lighter not working (visit to dealer failed to solve).

I-Drive has crashed once.

General Comments:

Overall I've been pleased with the 7 series. Performance is good considering the size of the car, and I've averaged 71.7 MPG according to the computer.

The computerised servicing system - which tells you when the car will next need to be serviced - seems to jump about a bit.

Lack of lumbar adjustment is sorely (literally) missed.

I-Drive is not as bad as generally thought, but is a pain when entering addresses in SatNav (as is the lack of full postcode support).

Odd that folding wing mirrors are not standard on such a large car.

Parking distance sensor can be fooled by posts.

Bluetooth a bit finicky with my iPhone.
