Which V50 to use?

Moin Moin, after a long time which car now comes into the house my wife has got into a V50. It will be one from about 04-06 with the 100-120 tkm. The question would be just which maschine? So at least 140 pesas should it be i.e. 2.4 or yet 2.4i or even T5? The consumption is rather subdued whereby my wife drives a lot of short distance..there makes hardly any sense a turbo (warm cold driving). I have read a few purchase advices, in it is from haufi A colleague once wrote that the first or fourth cylinder has no compression at any time with the 5 cylinders? What about it? How reliable is the automatic? Would be nice if the one or other V50 driver could give me a few tips Thanks
