While it's likely my failure to communicate effectively, my original reason for this latest service was to replace two light bulbs: one rear brake light and one front parking light. Once I dropped the car off I may have neglected to confirm that it was two bulbs that needed replacing. After your usual comprehensive inspection, it came to light that the car needed wheels, tires and wheel bearings, so my bulb replacement turned in to a pretty significant job, which was done to my satisfaction, except for the originally requested front parking light bulb replacement - it's still out - but not a big deal, we'll get it next time. Thanks for all of your hard work on my wife's TT.
