2008 Bentley Continental GT Speed 6.0 W12 from UK and Ireland
Without a doubt the best car I ever experienced
Nothing, but it has been owned for only a short time.
Without a doubt the finest car I have ever owned.
Re-mapped the ECU to 660 BHP, 820NM. Insanely fast, yet tame when light on the throttle.
How a 2450kg car can be so fast is astounding. The surge of acceleration is continuous and simply amazing.
The 10 mile commute to work returns 16 MPG through back lanes, A roads, traffic lights, roundabouts, and a short motorway stretch.
On a 250 mile run it averaged 22 MPG at 70-75mph before the re-map - which seems to have improved fuel use by perhaps 10%.
Driving slow or fast is a treat!
Would you buy another car from this manufacturer? Yes

A brief update on the Bentley...
Having used and enjoyed the car for a while now, a few faults have been experienced.
Engine misfiring which was diagnosed to be 2 ignition coils breaking down.
This was diagnosed using a snap on one scanner, searching the data files for the VW Phaeton. The Bentley uses Bosch Motronic ECUs, which are very common on other cars, so can be scrutinised without having to use a main dealer.
A spark plug had also been eroded, which could have been caused by the faulty coils.
Changing the above parts was straight forward, only requiring removal of the air boxes to get access. If other cylinders had faults, the intake manifold would likely have needed removing, but not in this case.
Testing on a 4wd rolling road, it made 669bhp and 957nm. This is remapped by Avon tuning, but still with standard exhaust system, filters/induction, turbos etc.
Loving the car and driving; it really feels like an occasion.

Update, update, update.
Engine misfiring continued.
The car has 33000 miles from new, and has been used for normal road driving only.
It appears to have run lean, which burned numerous valves and scored the cylinders. Engine is severely damaged.
No compression on 2 cylinders - which previously appeared as misfires.
Low and varied compression on the remaining cylinders.
Being an AluSil block (same manufacturer using method as Audi V8, Veyron W16... refinishing the bores is a very skilled and risk prone activity with little liability by those involved).
Replacement long block is Bentley's recommendation at a cost of £25350 (no typos).
Bentley were unhelpful; unwilling; slow, and are offering no goodwill in repairing the car.
Escalating the problem to the head of customer relations (who reports to Durheimer) resulted in dissatisfaction and rejection of the request for help.
Be warned Bentley will NOT help you if your car has issues.
Thanks to their dismissal my next Bentley will be an ASTON MARTIN.

Should you always be running 93 octane gas? Maybe someone ran 87 regular to save a few pennies.
