From memory I think the S3 was about 17k, this A5 is just under 19k.What was your ballon payment at the end with putting a grand in plus payments ?
I'm not bothered if it has equity at the end or not, as long as the monthly payment suit me then crack on! Expect nothing and you have no disappointments, equity is a bonus.
PS: The key is big discounts I got the A5 new cheaper than used ones were going for at the time.
