A couple of decades old engine with years of tried and tested reliability, or an engine designed by garlic eating surrender monkeys. I know where my money is lol. All down to opinion though, speak to Gary (gvk) on here who works on these day in day out, he says the 1.8 is by far the best for reliability. I just chose the one that gives the best economy, has no dpf, an egr valve you can blank and no coded injectors that are going to cost big bucks to fix. The 1.8 with 6spd box on paper also performs nearly the same as a 2.0, less than a second in it to 60. Good enough for me!
