Hi mate,
Firstly, congrats for the baby on the way
Your first? If so, then now's the time to sneak MPPSK in as it'll be a lot harder once little MashinBenzin is here!
I've just driven back from the Detailers having not been seen the car since Sat morning. Man it was good to be back, and the MPPSK was just awesome. I 100% believe it makes the car. It's brilliant.
Having been on holiday for a week and not been using the car for a few days, my mileage is at 1300 or so at present. But then again my daily commute is 75 miles, so it does rack up when I'm doing it. Probably why I get such good mpg!
