Wecome to the world of frontydom..
but can I throw a word of caution... we all have - (Dwifty..

et al - guilty as charged..

)occasionally have a fat fingered moment with typo's using the old keyboard at the wee small hours.. but.. be cautious -
a 'Fortera' with a 'mobilizer' and 'alam', and the 'milleg will chang daly due to youing' and you 'need to no anything pls ask'.. but the "de,tachable tow bar" sounds like a bargain.. for your car...
seriously - if they cant spell.. how on earth is it going to be looked after.... like a 'fewel fitter', or a 'oyel chaynje' - ask with the offer of bacon buttys and tea (beer works better!) for a second opinion....theres members close to you who will give you an honest opinion, theres no such thing as a dumb question... but losing your vectra and getting a knackered dog.. not a great idea.. look at it in daylight, on a dry day (rain hides minor dents and windscreen chips) with a "do i really need a 20-25 mpg $x$

'
not raining on your parade, BUT..
its a lot easier to walk away than it is to put one right, Martha was £65 (well £62.11 on ebay) as they managed to spell $X$ right (thats 4x4 on a laptop with the shift key on... which is how we met.. Me - Martha love affair - followed by abuse.. ) with 4 months tax and 9 months ticket, its worth £200 in scrap.. but for the smiles per miles - I'd never sell her.. used to be a Landrover fan.. now.. Frontys.. cheap, fixable with a set of spanners and a hammer.. and some carb cleaner..
Advice from me - walk away.. and thats just me..
If your after a LWB / 5 door.. post it in the wanted section on here.. sell Vectra privately.. better money..
