I have owned the car for nearly 2 years now and can only praise the car as it is a joy to drive and puts a smile on my face all the time. The brakes on the M5 are the only bad point I can make about the car and I have upgraded mine to a set of AP 6 Pots which has done the job and I will feel very happy with taking the car to the ring. The M5 is a good buy with prices for big motorway mile cars as low as 11k up to £25k for mint low mileage 03 plates. Remember these cars back in 99 were £60k with no spec so a lot of them are speced up to £70k so look what you get for your money. BMW E39 M5 Register
Favorite feature on my M5 has to be the double glazing as it makes it so quiet.
