Anyone looking to invest in Diesel still on here, I'm about to plug the plug on a 2 year Diesel lease deal, maybe in 2 years time I'll look and see where the market is with regards to Hybrid's and EV's.
If you have the requirements that mean a diesel is the most cost effective choice, then it’s still a good idea to get one. Generally, that is high annual mileage (>12,000).
Try to get a ULEZ compliant Euro6 if budget allows
