New road bike advice

Overpriced I'd say, maybe others will chime in.

In this person's defence, the bike does look basically like new, so you can look up stock pictures to get a better idea of the bike (not that that excuses the lack of pictures of course). It seems to be this one: https://www.evanscycles.com/bmc-teammachine-slr02-105-2017-road-bike-EV273212, last sold for ~£1.6k. The 2016 version got good reviews, e.g. here: https://www.bikeradar.com/road/gear/category/bikes/road/product/review-bmc-teammachine-slr02-105-50259/

Honestly, if it actually is in such a good condition with such little use, and there's proof of purchase as mentioned, and it is the 2017 version, I'd say it's not horribly overpriced at £950. That being said, I'd still say it should be a bit cheaper.
