in and around SE London/Kent i would definitely suggest D&T Wise in Bexleyheath. have been going there for 5 years, first with my E39 520 and more recently my 645. Have always felt the car is in good hands, and never felt like they were pulling a fast one. rates are much lower than stealers and wouldnt trust my car with anyone else!
