Thanks JJ - I actually had my timing chain done out at Paddock - I took the car out to them a couple of months after I bought the truck (late last year) and he took off the oil filter and saw little metal shavings so we thought "uh-oh, let's get this done now!" They were great, I would definitely take my car to them for the 'big stuff'. But it is a long way out for me (living in Snowmass Village) so was really hoping to find a decent Indy here on the Western Slopes (which I think I have found in European Autowerks in Glenwood Springs).
Jay - thanks for your comments too, you may well be right - I just assumed the front would be air-bags on my 4.6is as well but it's only the rears? That's good to know. Maybe I should just get that control module replaced (it sits in the trunk under the spare-wheel by the looks of things) - I've actually read somewhere else on Xoutpost that you need that module even if you are running coil-overs as it is needed to run the stability control and other things? If that's the case, and I have to have that replaced anyway, then perhaps I should just run with my new rear airbags (lifetime warranty with Arnott which is great) and just hope that the compressor doesn't go anytime soon?
