Yes I was reading the comments as I was thinking about buying the B5. The different points of view was very entertaining
You know the M5 had always been the epitome of motoring for me and I drove a lot of M5's before the B5 particularly, as you indicated it's rarity particularly in NZ. I believe there are or soon to be 4 here. And to be fair I would be driving an immaculate Blue E39 M5 or Black E61 M5 now if I'd had my ducks in a row at the time or it hadn't sold by the time I got there thankfully, as I hadn't driven the B5 by that stage.
The sound of the V10 on song and on the edge is hard to beat but IMO unless you're going hard it would be hard to live with particularly the SMG around town, at least and based on the 10 odd M5's I drove. The E39 M5 also sounds great and a excellent drive but when I drove the B5 with all the power of the E61 M5 plus the extra torque, good handling and the Alpina conversion sold me.
Having said that I was very wary of issues with the supercharger and the failures I had read about overseas. That the importance of using the right grade and type of oil at the prescribed service intervals is critical. Given the complete service history and work that had been carried out during it's life together with my mechanic saying inside the engine looked like new and the car had been well cared it was an easy decision and one I am very much enjoying.
It has an easy life just occasional weekends and long trips.
