Hi and welcome!
The 300C is a fantastic car. I will try to answer your questions below:
I will be doing high miles and this is one of the obvious car choices for me as its not your run of the mill but is it really a good long distance wafter? Can it reach the low 40's in mpg if I am careful with my speed or are we just talking 30's?
>> I get 26ish all town driving. It is possible to get 40ish in perfect conditions, but I would say mid 30's is normal
Do the seats have enough support for your back and are they good on long distances? Do the heated seats work ok - burn your bum or just mildly warm your cockles!
>> Seats are fantastic in my opinion. Heating has 2 levels, you can start it on 2 and it will go back to 1 once the heat gets up.
With the reduced number of Chrysler Stealers are there likely to be parts issues in the next couple of years?
>> Wouldn't think so.
I am looking for the 06/07 models in particular (I dont like the darker revised interior - it just looks dull and bland like all the german stuff but when was the revision actually done - as I have seen an odd 08 plate car with the old interior - are they just late registrations??
>> Yes, there were still some older models going about when they introduced the facelift. I prefer the older one too.
Is the SatNav worth having and is it easy to use? Touch screen or do you have to spend ages with a joystick type setup like on Nissan Birdview??
Postcode search available?
>> On the old model REJ the sat nav is pretty crap and is not touchscreen, but the sound quality of the unit is immense. The facelifts have the my-gig system which is far superior, touchscreen and built in hard drive. This is one of the few reasons to go for the facelift model. The old system uses DVD's which are well out of date even on the latest rev.
The boggo stereo unit is it fine? No issues with the knobs breaking - they look a bit weedy?
>> No experience on this one!
I know there is an issue with the alloys and I know the reasons why but is every single car effected or have they finally done something about it? Is it worth getting them sprayed with paint then varnished? I think they are just varnish on polished alloy are'nt they?
>> They will replace them under warranty, but a permanent solution is "still" being looked at by Chrysler. I wouldn't hold your breath there .....
What is the average price of a service for them?
>> Stealership £250 - £450 depending on service. Far better and cheaper using an independent as long as they use Chrysler parts there's no problem.
When did they introduce the auto headlights on switch on when you unlock the car and can you switch that option off?
>> It's been there since day 1 and can be disabled in the EVIC
How long have your tyres lasted and are the Pirrellis ok? I know camskill sell them for a reasonable £100
>> I'm over 20k and still on the first set. Some of the other guys can chime in here
The grille question! I do love the Bentley stylie one and I know you can get them off Ebay for about £300 - are they easy enough to fit - remove the original etc?
>> Yes, they take about 30 mins to fit, however I did it the other way and replaced the Bentley with the standard one!
Is the exhaust system stainless or mild steel?
>> Mild steel, although Startech do an expensive stainless option. I got my one with the car thankfully.
I have a lot of reading up to do on the forum for known issues but on the whole would you still recommend one and gut feel - are they built well enouhg to go the distance - I intend to keep it about 4 years at least!
>> Yes, swirl chamber aside they are very reliable in the whole. Read this thread, and if that doesn't convince you, nothing will. I've had mine over 2 years and apart from the swirl chamber issue it's been great. I really wouldn't part with it.

Thanks very much in advance sorry for the many questions?(sorry if I have missed the FAQ section somewhere!)
>> No problem, that's what we're here for.
Now, go buy that 300C and get grinning
