Now, that MV6 would look very nice on my drive in front of the black estate elite and I have a day off tomorrow. Price is top end but if it's a good one with cam belt history and all jobs done then £1795 sounds OK. Nitro you've seen it, is it worth the money 
With the kit and the leather, you wouldn't loose money on it... even if it needs a few bits and pieces.
I would suggest the price is a relative steal... must be worth a day out to make sure that it's rust free and mechanically sound if you're interested 
So Al Whats a basic check list on looking over this
TIA
Usual Omega bits...
Evidence of servicing, and by evidence I mean invoices, not a forged service book... Even a self maintained car will have some receipts... But looking for cambelt, wishbones, hbv, coolant condition, test everything to ensure it works as intended. Rust...wheel arches, door bottoms, front chassis legs. Drive it... Any clonks or knocks, odd handling traits, tyre wear. Do pedal trick... If this doesn't work suspect missing eml light.
Beyond that, usual second hand car stuff. Dvla vehicle check with reg and v5 number gives you Mot status, Vic marker ( if any), and Mot history and can all be done for free on a smart phone, so no excuses for not checking.
