i dont know, if you look hard yo can get a MK6 cheap. Got mine 59 plate from JCT600 Peugeot for £13,950 six months ago. Leathers, parking sensors, RNS510, 18" Monzas, Lux pack, Winter Pack etc...
Worth every penny, some small rattles which the MK5 also has. All can be fixed or suppressed.
Yes, ED30 and Pirelli are great, but 3-5 from now they will be very old and outdated. All depends what you want most....Power, Luxury, all rounded etc...
MK6 is the all round best one, just under powered to the ED30, but get a stage 1 map and you will be happy
