I'm bummed? Bought my 04 DII new - always maintained, premium gas, oil changes, dealer services, etc. Overheated in May - replaced thermostat. Again 2 weeks ago. Towed to mechanic. Engine is consuming coolant - mechanic says big problem. Says it I'll need a new engine soon. I drove it home (15 miles) no problem. It has to be my daily driver so I'm selling. It has a few other probs but I drove it daily for ~ 128K miles. I don't know what to ask for it - mechanic suggested $2000. I'll consider any offer.
