Thinking of swapping my 2009 TID for a Petrol 2004 T Vector or a petrol 2007 Aero as I'm not doing enough miles. (DPF filter the biggest worry as now working from home permanently because of covid) Question is should I? What do you think? All three cars are convertibles and are in very good condition and have a similar milage (Just over 100,000 miles on the clocks.)
