AI Market Summary

Solid mid-size diesel sedan with respectable fuel economy and lower CO2 tax band for Irish ownership. Practical boot and good visibility.
Market cooling sharply — 21% year-on-year price drop suggests oversupply of this generation. Current asking prices fair relative to comparable rivals, but watch for further negotiation room.
Infotainment freezing is widespread on 2020–2021 models; budget €400–800 for software update or replacement unit. DPF blockage common in city driving — confirm service history and recent regeneration cycles before purchase.
Request full service records showing DPF maintenance and oil analysis. Inspect engine oil dipstick colour (should be amber, not black) to flag oil dilution; dark colour suggests short-run usage and incomplete combustion.

Timing chain (non-interference) good for life. Budget for potential infotainment software update costs or auxiliary battery replacement if electrical issues arise.
