Hi all, looking to buy an Astra G Diesel but can't decide on which one. I believe the 1.7 DTI is considered to be the most reliable and seems to be the most numerous. Every once in a while I see an ECO4 model for sale, the lower tax is a nice bonus but curious if there is anything otherwise good or bad about them vs the standard model. I believe they have lowered suspension and different gear ratios amongst other things. If anyone has any experience of them I'm curious to know if they are any more economical in the real world, especially on the motorway, or if any parts (lowered suspension being an example) are difficult to find/expensive vs the standard model. 2.0 DTI is also appealing but seems very rare. Any advice appreciated.
