The original post asked whether £11990 was a good price for the TwinAir Lounge 105 with Volare Blue paint. This car (as described) lists at £13900. You usually can get about £1k off a dealer order, therefore an extra £900 or so seems a good deal.
Ok so they didn't describe if it had extra options, date of registration, but the more options the more expensive the list price, therefore the better the £11990 looks and they did say '14 reg' therefore at worst it's 5 months old. Even if '14 reg' means registered in 2014 rather than 14 plate, it's still a decent deal and I doubt it'd be older than March 2014 because the 105 engine has only recently started filtering through.
It's true you must consider the points that Jrkitching described but it's still a decent deal. As far as i'm concerned there's little to presume and the question is qualified enough to give a reasonable answer. A short sentence simply saying no new cars are good value might literally answer the question, but anyone acting reasonably would know that this was not what the OP was meaning. I stand by my earlier comments.
