Good choice, did you consider sensor pack in lieu of BMT for about same money? (cruise control, trip computer & rear park sensors) It's something I would have opted for if aware at time. However, if you drive in the City where conjestion charges apply the BMT is a good choice. I thought I'd achieve a higher MPG with the BMT but as it happens am averaging low 50's similar to others with the standard cars. Either way though I'm well happy with the car and am planning to keep long term dueto the low running costs (no road tax, £140 insurance and 50 plus MPG!)
