depends on the company and the sales person.
granted there are some rogues out there, but it is now a fairly professional industry. They are regulated by the FSA which helps a bit.
Things to bear in mind are:
how are you buying the car? Cash means you have saved up, not that you have a loan else where. personal loan? finance?
do you have a part ex?
what will make you feel you have had the best deal?
I used to come up against all the objections under the sun re: deal. At the end of the day, the only real important figure is the balance to change. IE, how much you have to give them for the car. have that set in your head, but be prepared to be educated as I’ll put £1 to your 1p that (if you have a px) it wont be worth what you think.
Then look at the finance if you are having it. set a weekly / monthly budget. STICK TO IT! you WILL get offered add ons and listen to them – some of them may make sense.
Legally, they can’t offer you a better deal for paying one way or the other, but be realistic. they’ll make more commission on a finance deal than not.
Also, in terms of the best discounts, they will be offered on cars that they garage have had in stock for a longer time. bear in mind though that the screen price may well have already been reduced so further reductions are not viable.
Always better to try and get discount through accessories. If you want a towbar that’ll cost you £500 – it won’t cost them that so in real terms you get a better offer
hope it helps.
what care are you looking to buy? may still know people that could help…?
