Am I right in saying that salespeople are less likely to give you the best deal possible if you pay cash, rather than take finance? (I’m thinking they get more commission from finance deals?)
All you can do is ask them. Finance commission isn't as great as people think, especially on low finance or zero rate deals, garages have to offer it as very few people can afford a car buying without finance and they can use it as a sales tool, i.e. they have everything at their fingertips to extend the term to make repayments lower, etc., to sell a higher value car!
If they have too many cars in stock or are approaching busy times when lots of part exchanges are due in, they'll be far more open to doing a deal to get rid of some stock and get some cash in the bank to aid cash flow.
You really need to establish good dialogue with them. Even when used prices are stupidly high at present, there's always a deal to be had. The garage won't be expecting to sell their cars at windscreen price, even today. You can always find ways of reducing the difference between your PX and the windscreen price of the car you're after. Some garages will "negotiate"on the value of your PX, others will throw in some "freebies" such as a new set of mats, a full tank of petrol, a "proper" spare tyre if it doesn't have one, an extended warranty, etc. For a car up at £14k and a PX of £2k,
I'd be starting negotiations at £10k and see where it goes. I'd also not conclude any deal same day - if you've not got them down far enough, then walk away (politely I mean, not strop off) - you'll often find you get a phone call the next day with an improved offer! - obviously make sure they have your name and number! We've never paid windscreen nor list price for any of our new or used cars. The last new car we bought was a 25% discount - list price was £20k and we "negotiated" them down to £15k. That took 10 days of "negotiation" where we basically stood our ground and they phoned us back every couple of days with an improved offer! Re used cars, windscreen prices may be high, but it's still a "negotiation" between buyer and seller - garages rely on people not wanting to be seen as "awkward" by bargaining/negotiating, so put high prices on cars in the expectation of "doing a deal". VERY few people pay list or windscreen price, so feel free to haggle hard.
