What's the deal with declaring mods on a used car you have bought? How is the average person meant to be able to tell if the car has been modded and in what way?
You're supposed to tell them anything relevant that you know about it. If you don't know then you can't tell them.
As long as you're truthful, and can back this up in court should a claim be refused, then you'll be okay.
Things like you buying it with electric seats when the car originally came with manual ones, or when it's had something retrofitted like cruise probably wouldn't void the insurance, and may not even affect the valuation.
However, telling them you didn't realise your car had a S54 engine in place of its normal 2.0 engine probably wouldn't wash.
You can use one of the VIN decoders to check what your car came with as standard though.
When a lorry scraped my car, and because the lorry driver was disputing liability, my insurance company paid me out initially. When it went to the bodyshop for a quote they told the insurance company the cost along with the cost of replacing the clear protection film I'd had fitted to the car. The insurance company didn't try to wriggle out of the claim, they simply refused to pay for the refitting of the film (about £500). I had to recover this from the other driver's insurance company, along with loss of earnings, car hire fees, excess, etc. as my insurance company wanted to go 50:50. It never got to court as the other driver's insurance caved in and paid (including reimbursing my insurer so there's no fault claim on my policy).
