Thanks in part to the standard fit diesel engine and high level of standard specification, the 508 isn’t what you’d call a bargain. Even the cheapest version is pricier than rivals from Ford, Vauxhall, Skoda and even the VW Passat. To make matters worse, it’s expected to lose almost three quarters of its value after just three years.
Stick to the basic manual saloon and carbon emissions are just 99g/km, helping keep benefit in kind (BIK) payments relatively low. Even the most powerful automatic emits just 110g/km, although the high list price means BIK payments will still be higher than some rivals.
The 508 range starts with the Active model that gets adjustable lumbar support, cruise control, rear parking sensors, dual-zone climate control, a 7.0in infotainment system with DAB radio, sat-nav, Android Auto and Apple CarPlay plus 17in alloy wheels.
The next step up is Allure that adds heated electric front seats, half leather seats, front parking sensors, a reversing camera, keyless entry and start, 18in wheels and a blind spot monitoring system. GT Line then adds different wheels, twin exhausts and full LED headlights.
At the top of the range is the GT that gets the most powerful engine, 19in wheels, full leather seats and a head up display. We’d advise sticking to Active trim as it has plenty of kit and you’ll minimise the amount of money you’ll lose. That said, you have to go up to Allure trim to get the 2.0-litre diesel.
All 508s get a raft of airbags and the usual electronic assistants but none have automatic braking, not even as an option. It does at least get a five star Euro NCAP safety rating.
