Can't fault that logic. Was thinking about infotainment today actually; that's where previous-gen cars are lagging in terms of the new ones. Bluetooth streaming/wireless charging, etc. That, and Volvo's satnav was absolute garbage. It came with a remote control FFS!2.4D (became the D4 I think?). Same engine as the D5 at 2.4 5 cylinders, just de-tuned to ~160bhp.
When I test drove the E-Class, I handed it back thinking that it felt very premium but didn't really offer an awful lot over the Volvo once you're up to speed and chewing up the miles. We're mainly changing to this because we wanted an estate and the deal was so good on finance that it wasn't much more than a Skoda Superb, due to the low depreciation.
The Volvo has fantastically comfy leather electric seats and a nice relaxing beige interior, but absolutely no infotainment and an agricultural and thirsty diesel engine, as well as limited boot space.
Apart from the relatively thirsty diesel engines, that's what put me off V70s a few years back. Loved my S90 but that cost £1500
Anyway, back to MBs
