Never sit around all day waiting for a punter, but with that size of stock view by appointment only don’t think works, people will enevitably let you down and not turn up. Keep busy, don’t waste time traipsing round auctions and being away from the site if that’s how you stock, do it online if you can across many websites.
get some proper legal advice on warranties T’s and C’s check, ask Lawjaw on here, he’s a member of lawgistics and could help. some aren’t worth the paper they’re printed on, we have a workshop and do most ourselves but still use WMS, shop around
the AutoTrader works best for us, love it or hate it, they’re expensive for a reason, they work. I have all 35 cars on their ranging from £5k up to £20k, any cheap part ex’s under a £1500 are free I think but only rarely put these on, it’s not just for expensive stuff. Don’t put your eggs in one basket though, I use the AutoTrader as main source of leads but always dabbling to see what works, whatever you use make sure you measure it, nothing worse than paying a fortune for advertising (our biggest bill) and not knowing if it works. Exchange and Mart is useless, where would you go to buy a car if you weren’t a dealer?
Above is only my opinion though AM, don’t want to sound like I’m telling you what to do mate, good luck with everything hope you’re a success (unless you’re based near me)
