FOr the finance guy to keep his job he has to have a given percentage of sales of these things, plus he's paid on commission and he likes to eat and have a roof over his head.
it's annoying, but it's his job.
that's changing today with the internet. And I avoid it by hitting up my credit union for a check - "i don't need any financing" and you have more control. When I bought my subaru that got me 1.2% interest rate instead of 2.4% from my credit union, and no add ons.
I have in the past used the extended warranty - to my benefit.
What i'm annoyed with now I got ziebart on our chevy truck (all trucks seem to rust out too fast) and find out a year later that you need to do the 'annual maintenance'...$50. fine. 3 years of that and 'oh, sorry, we made a mistake, it's a truck so it' $79/year'..so it's doubled the cost of ziebart then nearly doubled the annual cost.
so after 10ish years that's 1100ish more spent..but if we can keep the truck a year longer or have a rust free one for trade in/ sale it may be worth it. Unfortunately we're racking up more miles than planned...19k a year..so it may end up a moot point value wise.
All insurance is a gamble..I've paid car insurance for 35 years and had 3 claims. Paid homeowners for 22 and had 1 claim. Paid biz insurance for 12 and never had a claim. I've paid more in premiums than i've collected. And life insurance too.
