Nothing like having a freshly serviced M2 to drive around in. Fresh oil and filters, tyres rotated, wheels aligned, and a new layer of wax to make him look spiffy again. And floor mats vacuumed too -- a slight source of embarrassment for me because while I'm paying for his daily wash, that's only for the outside. Inside, I haven't bothered to maintain, so he was starting to get quite grungy where it matters most.
The main difference is that he's regained his responsiveness to the lightest touch. Have to remember to avoid my usual ham-fisted approach to gripping the wheel and stamping on the brakes. Not for the next 10,000 kliks, anyway.
