I look forward to you getting it and hearing your feedback.
It's not a bad car, it won't spontaneously combust and I highly doubt it'll ever let you down. There are lemons of all sorts of cars out there, Honda, Ford, Alfa, BMW and what not. But an ST220 is still a decent car, I feel that people lose sight of this and get into a war of stats and professional opinion. Are you really going to regularly drive the car up to its limits and really start to notice its inferiority in the corners compared to the DC2?
Or are you simply going to do what 90% of people do (but most wont ever care to admit) and park it on the drive and polish it, drive it it into town with the window down enjoying the sound of the V6, then take it onto the motorway and enjoy its acceleration in a straight line and occasionally chuck it around some decent A roads and enjoy its handling?
