I think you have some valid points.

There was a time when Chrysler had some of the best interior ergononics on the market.

In regards to the oil - synthetic oil has a much longer life than regular oil. I have always run a synthetic blend in my 03 Altima. Synthetic oil genrally offers better protection (less inclined to become viscous) during cold start ups, and does not break down as fast when hot. (more stable)

I have always advocated that oil and fluid changes are the least expensive maintenance you can perform for your car.

City driving necesitates more frequent oil changes as does cold weather. Short trips in cold weather, can build up significant condnesation in the oil pan. I never let my oil go past 5000 miles.

As a matter of interest it is easier on your motor when starting cold to drive it moderately to warm it up, than let it sit and idle.

In line coolant warmers vs. block heaters do a better job of heating the motor via plug in by circulating warm fluid through the cooling system, thus heating the engine.

If I can be honest, if you are driving in conditions that require tire chains for heavens sake purchase a different car...Like say an AWD Subaru...TThe Crossfire was never designed for the snow. It's light in weight and it's RWD The width of standard tire which holds like it's on rails during dry road condiditons, renders it useless in the snow. Think of all the sand and salt damage your car will incur during winter driving.

It's a sweet car...look after it.

P.S I'm looking forward to your Crossfire offroad report... ;-)
