It’s a nice boat. If you’re a bit handy you can fix items. The Gardner is a good engine. As are the boat builders of both boats.
As has been mentioned, don’t hang about. View the survey as offered. If it looks okay make a judgement. You won’t have a comeback to the surveyor, unless they agree to. Many people buy without survey. If you decide on having a survey, it’s up to you of course, May I say in my experience a full survey is money wasted. A hull and perhaps engine survey would do me. Rugby boats have a great reputation as far as I can see. I have no reason to think they wouldn’t guide you in the correct direction. (That’s my limited reputation gone!)
ETA. The bed pulls out as well. We did this to our bed a couple of years ago, after 16 years of ownership. It has made afifference. Wife can now sleep without having to touch me!!
