WITH its 3.5-litre V8, the 735iL is in direct competition with the Mercedes-Benz S-class. Running a long wheelbase and a considerable size, this front-engined, rear wheel drive limousine belies its bulk, both visually and in its on-road manners. Standard equipment is up there with the best of them and includes a front TV screen along with mobile telephone handset. A serious contender in the upper echelons of motoring.
