Look at one of these:
You know you want to. The 2.4 JTD 5cyl. is very good with power ranging from 136 to 185 hp and a 6mt. It drives beautifully. Only watch out that there is no play in the suspension, otherwise really reliable car, despite being an alfa. Give it a try or a testdrive
I found nineteen D5 V70's <?7000 on Autoscout. Then there's the 2.4D which is exactly the same sans some engine mapping. Now you have no reason not to buy one for your kids!
