Yes,No,maybe ?

Take the $4,400 and buy Apple stock. In about 6 years pay cash for a gently used 981 Boxster.

$15.9 is almost full retail on an 03S. Their price to me seems way too high for a car with a potentially expensive engine repair.

I would maybe trade even up for your car, but would consider they should throw in some cash before pulling the trigger on this deal.

The question is Why? Why do you want to trade year for year? Is the thought of the bigger motor that intriguing? Does your car need some major work that you are trying to avoid? Do the bells and whistles on the S make that much of a difference?

To me, you first would want to sell your car privately. For this sort of car, you will get way more for it. And then I would be looking at moving up into something newer - like an 05 or higher, or else what is the point? Why trade what you have for almost the same thing, except with more power?

$4400 + 27k miles - price differential between Base and S - That seems high
$15900 - I would like that for my 02S with 76K miles (No IMSB upgrade)

They are giving you $11500 for your car. For a dealer that's not bad

How bad do you want an 'S' punk?
I love my 'S'

I think with some research you could negotiate, especially if there are engine questions.
This 03 S needs a good PPI to understand what that tick is about. That's your determinator
So I say 'Maybe' if PPI is good and less cash

Remember - you are giving up 27k miles. That's 2-3 years of solid driving
