Might sound crazy, but we now answer the phones upto 10pm, and I also do very viewings til late over the weekend, most people are now working weekends until 5 pm so are very happy to be able to come see a car late on a weekend so it's a good thing to offer
The only one word if caution is that I try to really sus the customer out on the phone before suing a late viewing, as although it is rare things can go pear shaped
