I just bought one, collect it Tuesday, so thankfully found it before you did : )
There is one for sale on Autotrader (up North) through Motorpoint I think. If I recall correctly it is a 2013, 6K miles and up for around £21.5K. A little over your budget but if you want a super low mileage car ....
That car has dropped 1.5k since being put up for sale! I'm watching autotrader like a hawk lol It was also at the Burnley dealership at some point !
Yes i had noticed the price drop so enquired,but there are a few other charges so the price goes up to nearly £22.5k !!There is a 14plate Nismo near me for £24.5k with similar mileage,if i had the extra wonga thats where i'd be heading
