Exactly - best be safe than sorry!
But like I said, for the price of a facelift 140 you can get a pre-facelift 190. You'll have that fantastic engine and what not. You can always change the front bumper and rear lights for ones off Ebay to change the exterior to a facelift 190 then, so you're getting the best of both worlds.
But then again, a facelift 140 will have a darker, prettier dash, better dials, facelift rear lights and front bumper as standard, and a longer 6th gear ratio for quiet motorway cruising.
It's what you want out of it really mate. If you want one to be quieter and using a lot of motorway journeys, while not hugely bothered about speed, get the 140. If you wanted the 190 but just can't afford it, but can afford a facelift 140, then just get the pre-facelift 190.
