1999 Ford Contour Trouble?

Alright so I have a 99' Ford Contour and it's died on me right on the highway! While I was in drive going 60 mph also the reason how I figured out it had died was because the RPMS where going up and down and then all the lights came on like if I had powered off my vehicle…

How to get this cleaned in my car?

Is it possile to remove both the front 2seats of a car and do a full vaccum,
will it be a matter of just removing bolt and nuts and are there any welding involved.
mine is a 2004 ford card.4 door sedan
i'm taking it after 6months.want it give it a full vaccum.has some insects and pets formed in it.
what kind of cleaning should i go to get a full wash and vaccum

Declaring modifications to insurers

I have recently replaced my bumpers and alloys in an attempt to replicate a classic version of my car. Now, the stock alloy wheels which are FORD where 14" however I have swapped them out for a set of FORD 16" alloys. The same goes for the body kit, if it can be called that. Again the bumpers have been replaced for another genuine OEM part again which is a FORD part. So in essence all the mods, are not aftermarket but are genuine parts from the "hot hatch" version of the car. Do I need to declare these since these are still OEM parts therefore standard or not? If so would you imagine an increase in premium, I'm declaring my AFTERMARKET steering wheel tomorrow when it's fitted but I'm unsure about these standard parts.
