Audi A8 vs Mercedes S500L vs BMW 750i

After adjusting the front passenger seat of the cars to my sitting position, I got into their back-seats to find out which one of these offered the ultimate rear seat space and comfort. This explained the S-Class' predominance in this super-saloon segment. The 'S' has the best rear legroom and is the cosiest, closely followed by the A8 and the Seven. But what makes the A8 stand out is the power foot-rest that is integrated at the back of the front passenger seat. The front seat folds at the press of a button and a foot rest unfolds to let you stretch your legs, even the 10-inch entertainment adjusts automatically. Perks of travelling first class.
The A8 is a four seater with a fixed armrest and a control system that take up the rear centre seat, whereas the Beemer and Mercedes have foldable armrests equipped with cup-holders and climate controls. However, I doubt if anyone would like to be seated in the rear centre seat of these commodious cars and miss out on the luxury. For instance, the seat massage system is only available on the rear seats. I must mention that the A8 offers the best automotive rubdown I've ever experienced and wouldn't mind being stuck in the Mumbai traffic in it.
All the three luxury cars offer loads of goodies like infotainment screens, rear climate controls, massage function and electric window blinds, to name a few. And it goes without saying that all the three cars are well insulated from outside noise. Though the hushed interior isn't entirely a good thing as sitting underneath their hoods is the V-8 motor and my inner outlaw misses its beastly howl!
