Gracias! for your welcome.
The M5 is a fantastic car. It has astonishing performance but then you can go on a family trip (with the kids and a thousands of bags in the trunk) cruising at normal speeds and no big deal...
In my opinion, the best thing is the V10 engine. I had a 330i before the M5; if you drive it (the M5) below 4000 rpms, it kind of feels very similar to the 330i (obviously much more torque): very linear; but then you have 4000 rpms more, and it is when it really starts to kick ass. It feels like power is never going to stop coming.
The worst thing: the fuel tank capacity is very limited. It obviously is very thirsty, and you need to stop before reaching 300 kms. Daily consumption (mixed street and road driving) is 21.5 litres per 100 kms (11 mpg more or less); highway is 18 l/100 (13 mpg), and track is 40 l/100 (6 mpg)!!!!
I drove it at Jarama track (that old track outside Madrid where they used to race F1 and motorbikes world championships a thousand years ago) and times was pretty close to 911s (and I ain't no Fernando Alonso...):
.: Escuela Española de Pilotos :.: Ranking (35 on the list).
I would say it is the perfect choice if you have family and want a sporty car with great performance, and you just can buy one... I can surely tell you that when time comes, I will change this for another M5. By the way, I have had the car for 10 months and 13.000 kms and not a single visit to BMW (they even scrapped the 2.000 km revision, first is at 25.000 or 2 years, like any other new bimmer).
