SNAP - the exact same final two cars I am down to. I've just been out to the respective dealerships and sat in both. My thoughts:
ES: beautiful on the outside, exquisite on the inside. Lexus Teesside have a base trim + premium pack car which is what I'd get and I think I could drive to the moon and back on those seats without starting to ache. My gripe about the screen size and track pad felt like less of an issue because its gorgeous.
Volvo: would describe it as bold. Not the biggest fan of the rear end but prefer it to the G30 5-series (I had the previous generation F10 which looked better) and definitely better than the gopping E-class which looks like it has melted. Inside its enveloping, everything feels premium and the touch screen interface seemed fast and intuitive.
Then we come to the maths. Via Carwow I am being offered a bonkers 21% discount off a new T4 Momentum (3.9% APR). £8k off...! But I am want petrol, and I think I'll get mid 40s mpg at best on my 95 mile each way commute (almost all motorway). Lexus are offering 5% discount off ES Premium Pack and 5.9% APR to boot. Warranty wise both are 60k miles (or 18 months for me) but I can extend the Lexus warranty to 5 years / 140k miles and would expect it not to break. Can't extend the Volvo beyond 80k and their reputation for reliability seems to be behind them.
