Hi SP,
When I got the M5, the intention was to keep it for a short while and have some fun, just so I can say I've had one and wow it is an awesome machine!
When I bought the 5, I was speaking to a dealer (Sytner) and they just didn't seam interested in selling cars, they didn't return my calls or get the information I asked for, Targa are fairly close and I look at their website alot
viewed the car and test drove on a Thursday and drove it away on Friday!
With 4 children the options were limited for a large 7 seater (wife has an XC90 that is getting a bit tight) so have gone for a new GLS350d. Very, very different to the M5 but the family wagon needs to come first.
Maybe in 2/3 years the GLS will go to my wife and I will change the XC90 for the new M5. Who knows...
