5k is still a decent amount. They can be had for 3k, hell theres one for sale down the road from me, 1999 GTP with 120k on it, brand new Supercharger on it for $2700.

If you shop around, you could get a good GTP, and still have money to do **** to it.

Though, if you dont want to mod anything, or have a fun car, go with the Base.
