was about to get onto DPFs :) long journeys are must of vehicles fitted with DPFs, so high milage diesel suggests that it has been used alot which is good believe it or not hahaha.
this is the research i done before buying mine 8th gen:
* service history is must as you want reasurance that the vehicle and engine has been looked after.
* Check the clutch condition, private or empty road preferably, travel at quite a low speed and floor it in 2nd or 3rd to see if the clutch...
ah i see what you mean, just going from memory, on a motorway run, a honda accord type s 7th gen will do about 35 to 45mpg, so with a few sensible mods you could be up into the 50s?
