There are hardly any 03 Cupras on autotrader for £9k, most are more than that, so stick it on for £9k, or maybe £8995 - despite the high miles, you have FSSH, these engines are rock solid, you should get £8.5k, I certainly wouldn't expect to get less than £8k.
Those talking about Glass's guides, they're all very well, but apply to prices traders will pay - stick it on trader and you'll sell to a private buyer who doesn't use Glass's.
You have to consider that an LCR is a desirable car, often with peple upgrading from smaller hot hatches (like an
Ibiza Cupra), they may be in the market but only £8k to spend, so with most being £10k they'll not be able to get one, but will plump for a high mileage one for £8-£8.5k.
Get some photos up.
Oh, and that SatNav was a £2k option from new wasn't it - got to add a few quid.
